expiration dates of these options are 15 months, 18 months and 24 months from
the date of this prospectus.  Sales of shares by the selling shareholders may
be effected from time to time in one or more transactions, including block
trades, in the over-the-counter market, in negotiated transactions or in a
combination of any of these methods of sale.  The selling price of the shares
may be at the market price prevailing at the time of sale, at a price related
to such prevailing market price or at a negotiated price.  The selling share-
holders may be deemed "underwriters" within the meaning of the Securities Act
of 1933, as amended.  See "Plan of Distribution" on page 8 of this prospectus.

The Offering

  Common Stock offered by selling shareholders...................500,000 shares
  Shares underlying stock options held by selling shareholders.3,000,000 shares
  Common Stock to be outstanding after the offering, based on shares
  outstanding on July 23, 2004................................10,081,789 shares
  American Stock Exchange symbol............................................AEY

                                      3

     No shares are being offered or sold by us either directly or through
options or warrants.  The options have been granted to Barron Partners, L.P. by
David Chymiak and Kenneth Chymiak.  Thus, neither the sale of any of the
offered shares nor exercises of the options will result in an increase in the
numbers of outstanding shares of our common stock.  The total of 10,081,789
shares of common stock to be outstanding after this offering is based on the
number of shares outstanding on July 23, 2004 as reported on our Form 10-Q for
the period ended June 30, 2004.

     This is a continuous offering and is not underwritten.  We cannot predict
when or if the selling shareholders will sell their shares or exercise options
entitling them to purchase and possibly sell shares underlying the options.
This offering assumes that the selling shareholders will exercise all options
they hold for purchase of our common stock, for cash and at the current
exercise price.

                                   RISK FACTORS

     You should carefully consider the following risk factors, in addition to
the other information set forth in this prospectus, before deciding to purchase
any shares of our common stock.  Each of these risk factors could adversely
affect our business, operating results and financial condition, as well as
adversely affect the value of an investment in our common stock.  Additional
risks not presently known, or which we currently consider immaterial also may
adversely affect us.

We are highly dependent upon our principal executive officers who also control
us.

     David Chymiak, Chairman of the Board, and Kenneth Chymiak, President and
Chief Executive Officer, currently own approximately 80% of our outstanding
common stock and 100% of our outstanding preferred stock.  Our performance is
highly dependent upon the skill, experience and availability of these two
persons.  Should either of them become unavailable to us, our performance and
results of operations would probably be adversely affected to a material
extent.  In addition, they will continue to own a controlling interest in us
following this offering, thus restricting our ability to take any action
without their approval or acquiescence.  Likewise, as shareholders, they may
elect to take certain actions which may be contrary to the interests of the
other shareholders.

Our business is dependent on customers' capital budgets.

     Our performance is impacted by our customers' capital spending for
constructing, rebuilding, maintaining or upgrading broadband communications
systems. Capital spending in the telecommunications industry is cyclical. A
variety of factors will affect the amount of capital spending, and therefore,
our sales and profits, including:

   *     consolidations and recapitalizations in the cable television industry;
   *     general economic conditions;
   *     availability and cost of capital;
   *     other demands and opportunities for capital;
   *     regulations;
   *     demands for network services;
   *     competition and technology; and
   *     real or perceived trends or uncertainties in these factors.

     Developments in the industry and in the capital markets in recent years
have reduced access to funding for certain customers, causing delays in the
timing and scale of deployments of our equipment, as well as the postponement
or cancellation of certain projects by our customers.

     On the other hand, a significant increase in the capital budgets of our
customers might actually impact us in a negative fashion.  Much of our
inventory consists of refurbished and surplus-new equipment and materials that
we have acquired from other cable operators.  If our customers seek higher end,
more expensive equipment, the demand for our products may suffer.

                                      4

The markets in which we operate are very competitive, and competitive pressures
may adversely affect our results of operations.

     The markets for broadband communication equipment are extremely
competitive and dynamic, requiring the companies that compete in these markets
to react quickly and capitalize on change.  This will require us to make quick
decisions and deploy substantial resources in an effort to keep up with the
ever-changing demands of the industry.  We compete with national and inter-
national manufacturers, distributors, resellers and wholesalers including many
companies larger than we are.

    The rapid technological changes occurring in the broadband markets may
lead to the entry of new competitors, including those with substantially
greater resources than we have.  Because the markets in which we compete are
characterized by rapid growth and, in some cases, low barriers to entry,
smaller niche market companies and start-up ventures also may become principal
competitors in the future. Actions by existing competitors and the entry of new
competitors may have an adverse effect on our sales and profitability. The
broadband communications industry is further characterized by rapid
technological change. In the future, technological advances could lead to the
obsolescence of a substantial portion of our current inventory, which could
have a material adverse effect on our business.

Consolidations in the telecommunications industry could result in delays or
reductions in purchases of products, which would have a material adverse effect
on our business.

     The telecommunications industry has experienced the consolidation of many
industry participants, and this trend is expected to continue. We and one or
more of our competitors may each supply products to businesses that have
merged, such as AT&T Broadband and Comcast, or will merge in the future.
Consolidations could result in delays in purchasing decisions by the merged
businesses, and we could play either a greater or lesser role in supplying the
communications products to the merged entity. These purchasing decisions of the
merged companies could have a material adverse effect on our business. Mergers
among the supplier base also have increased, and this trend may continue. The
larger combined companies with pooled capital resources may be able to provide
solution alternatives with which we would be put at a disadvantage to compete.
The larger breadth of product offerings by these consolidated suppliers could
result in customers electing to trim their supplier base for the advantages of
one-stop shopping solutions for all of their product needs. Consolidation of
the supplier base could have a material adverse effect on our business.

Our success depends in large part on our ability to attract and retain
qualified personnel in all facets of our operations.

     Competition for qualified personnel is intense, and we may not be success-
ful in attracting and retaining key executives, marketing, engineering and
sales personnel, which could impact our ability to maintain and grow our
operations. Our future success will depend, to a significant extent, on the
ability of our management to operate effectively.  The loss of services of any
key personnel, the inability to attract and retain qualified personnel in the
future or delays in hiring required personnel, particularly engineers and other
technical professionals, could negatively affect our business.

We are substantially dependent on certain manufacturers, and an inability to
obtain adequate and timely delivery of products could adversely affect our
business.

     We are a Value Added Reseller and Master Distributor for Scientific-
Atlanta and a Value Added Reseller of Motorola broadband and transmission
products.  Should these relationships terminate or deteriorate, or should
either manufacturer be unable or unwilling to deliver the products needed by us
for our customers, our performance could be adversely impacted.  An inability
to obtain adequate deliveries or any other circumstance that would require us
to seek alternative sources of supply could affect our ability to ship products
on a timely basis. Any inability to reliably ship our products on time could
damage relationships with current and prospective customers and harm our
business.

                                      5

We have a large investment in our inventory which could become obsolete or
outdated.

     We have a large investment in inventory which could become obsolete or
outdated.  Much of our inventory is acquired from other cable operators and is
in the nature of used, refurbished, remanufactured or surplus new equipment.
Determining the amounts and types of inventory requires us to speculate to some
degree as to what the future demands of our customers will be.  If, because of
technological changes, consolidation in the industry or competition from other
types of broadcast media, the demands for our inventory could be reduced
substantially, which would have a material adverse effect upon our business and
financial results.

Our outstanding common stock is very thinly traded.

     While we have approximately 10.1 million shares of common stock
outstanding, 74.14% of these shares are beneficially owned by David Chymiak and
Kenneth Chymiak and 4.96% are beneficially held by Barron Partners, L.P.  As a
consequence, only about 21% of our shares of common stock are held by
nonaffiliated, public investors and available for public trading.  The average
daily trading volume of our common stock is low.  As long as this situation
exists, once the shares may be sold in the public market, it may be difficult
for shares of our stock to be sold without materially affecting the demand and,
consequently, the market price of our shares.  Thus, investors in our common
stock may encounter difficulty in liquidating their investment in a timely and
efficient manner.

We have not paid any dividends on our outstanding common stock and have no
plans to pay dividends in the future.

     We have not paid any dividends on our common stock.  We currently plan to
retain our earnings and have no plans to pay dividends on our common stock in
the future. We may also enter into credit agreements or other borrowing
arrangements which may restrict our ability to declare dividends on our common
stock.

Our principal executive officers and shareholders have a number of conflicts of
interest with us.

     Certain of our key properties are leased from entities owned by our
principal executive officers.  Also, these executives have made loans to us in
various amounts in the past and are paid interest on these loans. These
transactions are described in the proxy statement that is incorporated by
reference into this prospectus. These arrangements create certain conflicts of
interest between these executives and us that may not always be resolved in a
manner most beneficial to us.

Our international operations may be adversely affected by a number of factors.

     Although the majority of our business efforts are focused in the United
States, we have international operations in the Philippines, Taiwan, Korea,
Japan, Australia, Brazil, Ecuador, Dominican Republic, Honduras and a few Latin
American countries.  We currently have no binding agreements or commitments to
make any material international investment.  Our foreign operations may be
adversely affected by a number of factors, including:

    *   local political and economic developments could restrict or increase
        the cost of our foreign operations;
    *   exchange controls and currency fluctuations;
    *   tax increases and retroactive tax claims could increase costs of our
        foreign operations;
    *   expropriation of our property could result in loss of revenue, property
        and equipment;
    *   import and export regulations and other foreign laws or policies could
        result in loss of revenues; and
    *   laws and policies of the United States affecting foreign trade,
        taxation and investment could restrict our ability to fund foreign

                                  USE OF PROCEEDS


     We will not receive any of the proceeds from the sale of shares of common
stock offered by this prospectus.

                            SELLING SECURITY HOLDERS

Background

     On September 24, 2004, David E. Chymiak, our Chairman of the Board and
owner of approximately 41.5% of our outstanding common stock and 50% of our
outstanding preferred stock, and Kenneth A. Chymiak, our President and Chief
Executive Officer and owner, together with his wife, of approximately 37.6% of
our outstanding common stock and 50% of our outstanding preferred stock,
entered into a stock purchase agreement with Barron Partners, L.P., a Delaware
limited partnership whose main offices are in New York, New York, pursuant to
which Barron Partners agreed to purchase from the Chymiaks 500,000 shares of
our common stock at a price of $3.25 per share.  These shares purchased by
Barron Partners represent approximately 4.96% of our outstanding shares of
common stock, based on the number of our outstanding shares at June 30, 2004.
Bathgate Capital Partners, LLC received a fee of $97,500 in connection with
the sale of the 500,000 shares and will receive additional fees if and to the
extent that the options are exercised.

     Under the stock purchase agreement, Barron Partners was also granted three
options to buy up to an additional 3,000,000 shares of common stock from the
Chymiaks.  The terms of these options are summarized as follows:




    Option      No. of Shares     Exercise Price       Expiration Date
                                          
    No. 1        1,000,000            $4.25        15 months from date of
                                                        prospectus 1
    No. 2        1,000,000            $5.25        18 months from date of 
                                                        prospectus 1
    No. 3        1,000,000            $6.25        24 months from date of
                                                        prospectus 1

---------------------------
1 The expiration date of each option shall be extended by the amount of time,
if any, during which Barron Partners is restricted from selling any securities
described in this prospectus due to the implementation of a "Black-out Period"
by us pursuant to the stock purchase agreement.

                                      7


Each option can be exercised at any time in whole or in part, except that each
exercise must be for a minimum of 150,000 shares.  The stock purchase agreement
provides that the options are not exercisable to the extent that shares
received upon exercise, when added to the shares that Barron Partners then
beneficially owns, would represent more than 4.99% of our outstanding shares.
This restriction can be eliminated by Barron Partners upon 61 days' prior
written notice.  The 3,500,000 shares covered by the stock purchase agreement
represent approximately 34.7% of our outstanding shares of common stock.

     All of the shares which Barron Partners has the right to acquire under the
terms of the stock purchase agreement, including the shares which they are
entitled to receive upon exercise of the options, may be offered for sale from
time to time by the selling shareholders pursuant to this prospectus.  The term
"selling shareholders" as used in this prospectus, includes Barron Partners,
L.P. and their transferees, pledges, donees and other successors acquiring an
interest in the shares after the date of this prospectus.

     The selling shareholders are not obligated to sell their shares.  If they
do sell their shares, they may be sold pursuant to this prospectus or in
another permitted manner.  Thus, no assurances can be given as to the number of
shares that may be sold by the selling shareholders or that will be held by
them upon completion of the sales.  Information concerning the selling share-
holders may change from time to time and the changed information will be
presented in a supplement to this prospectus if and when necessary and
required.  We do not know whether or when the options will be exercised or how
long the selling shareholders may hold their shares before selling them.  We
currently have no agreements, arrangements or understandings with any of the
selling shareholders regarding sales of their shares.

     Barron Partners, L.P. has not had a material relationship with us or any
of our subsidiaries within the past three years.  They also have sole voting
and investment power with respect to the shares they acquire pursuant to the
stock purchase agreement.




                            PLAN OF DISTRIBUTION

     We are registering the offer and sale of the shares covered by this
prospectus on behalf of the selling shareholders.  As used in this prospectus,
the term "selling shareholders" includes donees, pledgees, transferees or other
successors-in-interest selling shares received from a selling shareholder after
the date of this prospectus.  The selling shareholders will act independently
of us in making decisions with respect to the timing, manner and size of each
sale.

     The selling shareholders may sell their shares from time to time in one or
more types of transactions (which may include block transactions) on the
American Stock Exchange, in the over-the-counter market, in negotiated
transactions, through put or call options transactions relating to the shares,
through short sales of shares, or a combination of these methods of sale, at
market prices prevailing at the time of sale, at negotiated prices, or at
varying prices determined at the time of sale.  These transactions may or may
not involve brokers or dealers.  The selling shareholders have advised us that
they have not entered into any agreements, understandings or arrangements with
any underwriters or broker-dealers regarding the sale of their shares, nor is
there an underwriter or coordinating broker acting in connection with the
proposed sale of shares by the selling shareholders.

     The selling shareholders may sell their shares directly to purchasers or
to or through broker-dealers, which may act as agents or principals.  These
broker-dealers may receive compensation in the form of discounts, concessions,
or commissions from the selling shareholders and/or the purchasers of shares
for whom these broker-dealers may act as agents or to whom they sell as
principal, or both (which compensation as to a particular broker-dealer might
be in excess of customary commissions).

     The selling shareholders also may resell any of their shares that qualify
for sale under Rule 144 in open market transactions pursuant to Rule 144 under
the Securities Act, rather than pursuant to this prospectus.

                                      8

     The selling shareholders and any broker-dealers that act in connection
with the sale of their shares might be deemed to be "underwriters" within the
meaning of Section 2(11) of the Securities Act, and any commissions received by
these broker-dealers and any profit on the resale of the shares sold by them
while acting as principals might be deemed to be underwriting discounts or
commissions under the Securities Act.  We have agreed to indemnify the selling
shareholders against certain liabilities, including liabilities arising under
the Securities Act.  The selling shareholders may agree to indemnify any agent,
dealer or broker-dealer that participates in transactions involving sales of
their shares against certain liabilities, including liabilities arising under
the Securities Act.

     Because the selling shareholders may be deemed to be "underwriters" within
the meaning of Section 2(11) of the Securities Act, the selling shareholders
will be subject to the prospectus delivery requirements of the Securities Act.
We have informed the selling shareholders that the anti-manipulative provisions
of Regulation M promulgated under the Exchange Act may apply to their sales in
the market.

     Upon notification to us by a selling shareholder that any material
arrangement has been entered into with a broker-dealer for the sale of shares
through a block trade, special offering, exchange distribution or secondary
distribution or a purchase by a broker or dealer, a supplement to this
prospectus will be filed, if required, pursuant to Rule 424(b) under the
Securities Act, disclosing:

     *     the name of the selling shareholder and of the participating
           broker-dealer(s);
     *     the number of shares involved;
     *     the price at which the shares were sold;
     *     the commissions paid or discounts or concessions allowed to the
           broker-dealer(s), where applicable;
     *     that the broker-ealer(s) did not conduct any investigation to
           verify the information set out or incorporated by reference in this
           prospectus; and
     *     any other facts material to the transaction.

     We will pay all the costs, expenses and fees related to the registration
of the shares offered by this prospectus.  The selling shareholders will be
responsible for the payment of any brokerage commissions, underwriting fees or
discounts or fees or expenses of counsel or advisors attributable to the sale
of the shares.

     The validity of the shares of our common stock being offered hereby is

         Total                                         $       10,000




Item 15.  Indemnification of Directors and Officers.

     The registrant's Certificate of Incorporation, as amended ("Certificate of
Incorporation") and Bylaws provide that each person who was or is made a party
to, or is involved in, any action, suit or proceeding by reason of the fact
that he or she was a director, officer, employee or agent of the registrant (or
was serving at the request of the registrant as a director, officer, employee
or agent for another entity) will be indemnified and held harmless by the
registrant, to the fullest extent not prohibited by the laws of Oklahoma.

     Under Section 1031 of the Oklahoma General Corporation Act (the "OGCA"), a
corporation may indemnify a director, officer, employee or agent of the
corporation against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by him or her if he
or she acted in good faith and in a manner he or she reasonably believed to be
in or not opposed to the best interests of the corporation and, with respect to
any criminal action or proceeding, had no reasonable cause to believe his or
her conduct was unlawful.  In the case of an action brought by or in the right
of a corporation, the corporation may indemnify a director, officer, employee
or agent of the corporation against expenses (including attorneys' fees)
actually and reasonably incurred by him or her if he or she acted in good faith
and in a manner he or she reasonably believed to be in the best interests of
the corporation, except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable to the corporation unless a court finds that, in view of all the
circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such expenses as the court shall deem proper.

     The OGCA permits Oklahoma corporations to include in their certificates of
incorporation a provision eliminating or limiting director liability for
monetary damages arising from breaches of their fiduciary duty.  The
Certificate of Incorporation provides that to the maximum extent permitted by
law, a director of the registrant shall not be liable to the registrant or its
shareholders for monetary damages for breach of fiduciary duty as a director.
The only limitations imposed under the OGCA and the Certificate of
Incorporation are that a director's liability will not be limited:  (i) for
breaches of the director's duty of loyalty to the corporation or its
shareholders, (ii) for acts or omissions not in good faith or involving
intentional misconduct or known violations or law, (iii) for the payment of
unlawful dividends or unlawful stock purchases or redemptions, or (iv) for
transactions in which the director derived an improper personal benefit.

                                    II-1

     The foregoing summaries are necessarily subject to the complete text of
the statutes, the Certificate of Incorporation and Bylaws referred to above and
are qualified in their entirety by reference thereto.

Item 17. Undertakings.

   (a)  The undersigned registrant hereby undertakes:
        (1)   To file, during any period in which offers or sales are being
   made, a post-effective amendment to this Registration Statement to:

             (i)  include any prospectus required by Section 10(a)(3) of the
        Securities Act of 1933;

            (ii)  reflect in the prospectus any facts or events arising after
        the effective date of the Registration Statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the Registration Statement.  Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the low or high end of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the Securities and Exchange Commission pursuant to Rule 424(b) if,
        in the aggregate, the changes in volume and price represent no more
        than a 20% change in the maximum aggregate offering price set forth in
        the "Calculation of Registration Fee" table in the effective
        Registration Statement; and

           (iii)  include any material information with respect to the plan of
        distribution not previously disclosed in the Registration Statement or
        any material change to such information in the Registration Statement;

   provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) above do not
   apply if the information required to be included in a post-effective
   amendment by those paragraphs is contained in periodic reports filed by the
   registrant pursuant to Section 13 or Section 15(d) of the Securities
   Exchange Act of 1934 that are incorporated by reference in this Registration
   Statement.

        (2)   That, for the purpose of determining any liability under the
   Securities Act of 1933, each such post-effective amendment shall be deemed
   to be a new registration statement relating to the securities offered
   therein, and the offering of such securities at that time shall be deemed to
   be the initial bona fide offering thereof.

        (3)   To remove from registration by means of a post-effective
   amendment any of the securities being registered which remain unsold at the
   termination of the offering.

                                    II-2

   (b)  The undersigned registrant hereby undertakes that, for purposes of
   determining any liability under the Securities Act of 1933, each filing of
   the registrant's annual report pursuant to Section 13(a) or Section 15(d) of
   the Securities Exchange Act of 1934 (and, where applicable, each filing of
   an employee benefit plan's annual report pursuant to section 15(d) of the
   Securities Exchange Act of 1934) that is incorporated by reference in this
   Registration Statement shall be deemed to be a new registration statement
   relating to the securities offered therein, and the offering of such
   securities at that time shall be deemed to be the initial bona fide offering
   thereof.

   (c)  Insofar as indemnification for liabilities arising under the Securities
   Act of 1933, may be permitted to directors, officers and controlling persons
   of the registrant pursuant to the provisions discussed in Item 15 above, or
   otherwise, the registrant has been advised that in the opinion of the
   Securities and Exchange Commission such indemnification is against public
   policy as expressed in the Act and is, therefore, unenforceable.  In the
   event that a claim for indemnification against such liabilities (other than
   the payment by the registrant of expenses incurred or paid by a director,
   officer or controlling person of the registrant in the successful defense of
   any action, suit or proceeding) is asserted by such director, officer or
   controlling person in connection with the securities being registered, the
   registrant will, unless in the opinion of its counsel the matter has been
   settled by controlling precedent, submit to a court of appropriate
   jurisdiction the question whether such indemnification by it is against
   public policy as expressed in the Act and will be governed by the final
   adjudication of such issue.
