<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Some of the statements in this prospectus and in documents incorporated by reference constitute "forward-looking statements" within the meaning of the U.S.
Private Securities Litigation Reform Act of 1995. These statements relate to future events or our future financial performance, including the successful integration of our recent acquisition of
Celiant Corporation, which involve known and unknown risks, uncertainties and other factors that may cause our actual results, levels of activity, performance or achievements to be materially
different from those expressed or implied by any forward looking statements. In some cases, you can identify forward looking statements by terminology such as "may," "will," "could," "would,"
"should," "expect," "plan," "anticipate," "intend," "believe," "estimate," "predict," "potential" or "continue" or the negative of those terms or other comparable terminology. These statements are
only predictions. Actual events or results may differ materially because of market conditions in our industries or other factors. Moreover, we do not, nor does any other person, assume responsibility
for the accuracy and completeness of those statements. Unless otherwise required by applicable securities laws, we disclaim any intention or obligation to update any of the forward-looking statements
after the date of this prospectus to conform them to actual results. All of the forward-looking statements are qualified in their entirety by reference to the factors discussed under the captions
"Risk Factors" in this prospectus and any applicable prospectus supplement and "Management's Discussion and Analysis of Financial Condition and Results of Operations" of our most recent
Form&nbsp;10-K and subsequently filed Form&nbsp;10-Qs (incorporated by reference in this prospectus) and similar sections in our future filings that we incorporated by
reference in this prospectus, which describe risks and factors that could cause results to differ materially from those projected in those forward-looking statements. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
caution you that these risk factors may not be exhaustive. We operate in a continually changing business environment, and new risk factors emerge from time to time. We cannot predict
these new risk factors, nor can we assess the impact, if any, of these new risk factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ
materially from those projected in any forward-looking statements. Accordingly, forward-looking statements should not be relied upon as a prediction of actual results. In addition, our estimates of
future operating results are based on our current business, which is constantly subject to change as our strategy evolves. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We are a multinational supplier of communications products and systems to worldwide commercial, industrial, and governmental customers. Our products are related
to our core competency&#151;the radio frequency (RF) path. We have unique technical skills and marketing strengths in developing products for RF systems. Our products are sold principally to
four key markets: wireless infrastructure, fixed-line telecommunications, broadcast and government, and wireless accessories. The wireless infrastructure market is based on infrastructure
for wireless communication providers, such as cellular and Personal Communications Service (PCS) providers. The fixed-line telecommunications network market is based on infrastructure for
public telecommunication network operators and competitive service providers for voice, data, video and Internet service. The broadcast and government market is based on infrastructure systems for
radio and television broadcasting, including digital TV, multichannel video and satellite delivered broadcast services, air traffic control, weather surveillance radar, and high frequency applications
for government and commercial applications. The wireless accessories market is based on products such as mobile antennas for cellular, PCS, Specialized Mobile Radio (SMR) and paging services. This
market also includes products such as hands-free solutions for mobile phones and wireless antennas and global positioning systems components sold to automotive manufacturers and suppliers. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our
principal products include coaxial cables, connectors, cable assemblies and accessories, microwave antennas for point-to-point communication systems,
television broadcasting antennas, special purpose antennas for commercial and government use, antennas and earth stations for satellite communication systems, cellular antenna products, power
amplifiers, cellular telephone accessories, Global Positioning System (GPS) antennas and products, equipment shelters, radar system components and related ancillary items and services. These products
are frequently sold as integrated subsystems and systems rather than as separate components. With the recent acquisition of Celiant Corporation we have become a leading merchant supplier of RF
amplifiers in the U.S. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
conduct manufacturing operations primarily from ten locations in the United States and from nine locations in other countries. Sales by non-U.S. operations and export
sales from U.S. operations accounted for approximately 50% of our net sales in 2001, 50% in 2000 and 51% in 1999. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
are a Delaware corporation. Our principal executive offices are located at 10500 West 153<SUP>rd</SUP> Street, Orland Park, Illinois 60462, and our telephone number is
(708)&nbsp;349-3300. </FONT></P>

factors relate principally to our business and the industry in which we operate. Other factors relate principally to your investment in our common stock. The risks and uncertainties described below
are not the only ones facing our company. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also adversely affect our business and

<P><FONT SIZE=2><B>Our quarterly and annual operating results may vary, which could cause a decline in the price of our common stock.  </B></FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Historically, our quarterly and annual sales and operating results have fluctuated. We expect fluctuations to continue in the future. In addition to general
economic and political conditions, the following factors affect our sales: the timing of significant customer orders; our inability to forecast future sales due to our
just-in-time supply approach; changes in competitive pricing; wide variations in </FONT></P>

profitability by product line; variations in operating expenses; the timing of announcements or introductions of new products by us, our competitors or our respective customers; the acceptance of
those products; relative variations in manufacturing efficiencies and costs; and the relative strength or weakness of international markets. </FONT></P>


<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Since
our quarterly and annual sales and operating results vary, we believe that period-to-period comparisons are not necessarily meaningful, and you should not
rely on those comparisons as indicators of our future performance. Due to the foregoing factors, it is possible that in some future quarter or quarters our revenues or operating results will not meet
the expectations of the public stock market analysts or investors, which could cause the price of our common stock to decline. </FONT></P>

<P><FONT SIZE=2><B>The market price of our common stock is volatile, and you may not be able to resell shares of our common stock at or above the price you paid for them.  </B></FONT></P>


<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We believe the price of our common stock fluctuates in response to our actual or anticipated quarterly and annual orders, sales, net income and cash flow; changes
in general economic conditions; reliance on international markets; changes in analysts' expectations, estimates and recommendations; and news
reports regarding us, our competitors and our markets. In addition, the U.S. stock market in general and telecommunications stocks in particular have been extremely volatile. These broad market and
industry fluctuations may adversely affect the price of our stock, regardless of our actual operating performance. In addition, delays or postponements of wireless infrastructure deployments,
including 3G technology, may adversely affect the price of our stock, regardless of whether such deployments have an actual impact on our orders or sales. We expect that the price of our common stock
will fluctuate in the future, perhaps substantially. </FONT></P>

<P><FONT SIZE=2><B>Current economic and political conditions are uncertain.  </B></FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Conditions in the domestic and global economies are extremely uncertain. The terrorist attack in 2001, current conflicts in the Middle-East and the
potential for future terrorist attacks have created many economic and political uncertainties that have severely impacted the global economy, and it is difficult for us to predict the
long-term effects of these uncertainties on our business. Weak domestic and international economic conditions have had a material negative effect on the worldwide telecommunications
industry. Since early 2001, the industry has experienced a significant decline in revenue and product orders. This decline has resulted, and may continue to result, in the reduction of capital
expenditure budgets and the delay in product orders and, in turn, decreased demand for our products. While we are optimistic about long-term prospects, the rate at which the
telecommunications industry improves is critical to our ability to improve our overall financial performance. </FONT></P>

<P><FONT SIZE=2><B>We continue to experience intense competition and pricing pressure, and if we are unable to compete successfully, we may lose market share.  </B></FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We believe that to be profitable in the future we must respond effectively to increased competitive pressure. The communications equipment industry is extremely
competitive and is characterized by rapid technological change, new product development and product obsolescence, evolving industry standards and significant price erosion over the life of a product.
Our growth depends significantly upon our ability to enhance our existing products and to introduce new products on a timely basis. We consider our principal competitive factors to include product
quality and performance, service and support, pricing and proprietary technology. Over the past several years, in response to aggressive pricing practices by our competitors, we have significantly
lowered prices for most of our products. In addition, the ongoing consolidation within the telecommunications industry has given our customers substantial purchasing power, which contributes to
additional pricing pressure. If we are unable to compete successfully, we may lose market share. We expect that a significant loss in market share would have a material negative effect on our
business, financial condition and operating results. </FONT></P>

<P><FONT SIZE=2><B>A substantial portion of our sales are outside the U.S., and conducting business in international markets involves risks and uncertainties that may impact our operating
results.  </B></FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A significant portion of our sales are outside the U.S., and in recent years we have significantly increased our international manufacturing capabilities. We
anticipate that international sales will continue to represent a substantial portion of our total sales and that continued growth and profitability will require further international expansion.
Identifiable foreign exchange rate exposures result primarily from currency fluctuations, accounts receivable from customer sales, the anticipated purchase of products from affiliates and third-party
suppliers and the repayment of intercompany loans with foreign subsidiaries denominated in foreign currencies. International business risks also include political and economic instability, tariffs and
other trade barriers, longer customer payment cycles, adverse taxes, restrictions on the repatriation of earnings, expropriation or requirements of local or shared ownership, compliance with local
laws and regulations, terrorist attacks, developing legal systems, reduced protection of intellectual property rights in some countries, cultural and language differences, and difficulties in managing
and staffing operations. We believe that international risks and uncertainties could materially impact our future sales, financial condition and operating results. </FONT></P>

<P><FONT SIZE=2><B>Our inability to effectively integrate Celiant into our existing business or unexpected costs or difficulties associated with the acquired business could negatively impact us.  </B></FONT></P>


<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our recent acquisition of Celiant presents financial, managerial and operational challenges, which may divert some of management's attention from running our
existing business. Celiant is a much larger business than those that we have previously acquired. We must pay particular attention to the integration of products, processes, personnel and culture,
including: the response of the acquired business to integration into our organization; our ability to successfully manage the operations of the acquired business; and the profitability and growth of
the acquired business. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
may be unable to integrate Celiant's technology, operations and personnel successfully, which could negatively impact our business. Customer dissatisfaction or performance problems
with the acquired business could also have a material adverse effect on our reputation and business. In addition, the acquired business could underperform relative to our expectations. We also could
experience financial or other setbacks if the acquired business has problems or liabilities of which we are not aware or that are significantly more extensive that we anticipate. </FONT></P>

<P><FONT SIZE=2><B>The sales and profitability of our RF Power Amplifiers Group, which represents a significant portion of our business, are dependant upon our relationship with Lucent and on the
availability of certain key components.  </B></FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;With our acquisition of Celiant, our RF Power Amplifiers Group will account for a significant portion of our sales. The Group sells the vast majority of its
products to one customer, Lucent Technologies&nbsp;Inc. We are party to a supply agreement with Lucent pursuant to which Lucent has committed to purchase from us at specified prices a minimum of
$275&nbsp;million of products in 2002, $350&nbsp;million of products in
2003 and $425&nbsp;million of products in 2004, subject to certain adjustments. The agreement is effective until August&nbsp;31, 2006; however, after 2004 there are no firm commitments for orders.
Lucent has indicated a desire to renegotiate the contract, and we have commenced discussions to reach mutually beneficial terms. If such negotiations result in a reduction in Lucent's commitment or if
Lucent were unable or unwilling to perform its obligations under that agreement, sales of our radio frequency (RF) power amplifiers would decline, which could result in decreased profits. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The markets in which we and our customers compete are characterized by rapidly changing technology, rapid product obsolescence, evolving industry standards,
continuous improvements in products and services and significant price erosion over the life of the product. We believe that our future success depends on our ability to effectively anticipate and
respond to changes in technology, customer needs and industry standards. Failure to anticipate changes, to adapt current products, to develop and introduce new products on a timely and
cost-competitive basis or to gain market acceptance for new products would impair our competitiveness and could have a material negative impact on our business and operating results. </FONT></P>


<P><FONT SIZE=2><B>Our customers' spending patterns and ability to obtain financing affects demand for our products and, in turn, our sales and profitability.  </B></FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Demand for our products is influenced by our customers' spending patterns and ability to obtain financing. Our sales trends are impacted by customer spending on
non-Andrew-provided infrastructure such as base station radios, software and switching equipment. Customer spending on new frequency spectrum licenses has resulted in delays in deployment
of 3G technology, which, in turn, may cause fluctuations in sales of our wireless infrastructure products. </FONT></P>

<P><FONT SIZE=2><B>Consolidation in the telecommunications industry may impact our business.  </B></FONT></P>


<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The telecommunications industry has experienced significant consolidation, and this trend is expected to continue. It is possible that we and one or more of our
competitors each supply products to the companies that have merged or will merge. This consolidation could result in delays in purchasing
decisions by merged companies or in us playing a decreased role in the supply of products to the merged companies. </FONT></P>

<P><FONT SIZE=2><B>Our failure to protect our intellectual property rights could negatively affect our business prospects and ability to compete effectively and, ultimately, our operating
results.  </B></FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Others could obtain or use our intellectual property without our permission, develop equivalent or superior technology or claim that we have infringed on their
intellectual property rights. We rely on a combination of patent, copyright, trademark and trade secret laws, and non-disclosure and non-competition agreements to protect our
rights, but there can be no assurance that these measures will adequately protect our property rights or that our proprietary information will not otherwise become known or be independently developed
by our competitors. We are dependent on our intellectual property rights as a whole; however, we do not believe that the loss of exclusivity with respect to any one right would have a significant
negative impact on our business, financial condition or operating results. If a third party succeeded in making an infringement claim against us or our customers and either we are unable to license
the technology on commercially reasonable terms or a "design around" is not practicable, our business, financial condition and operating results could suffer. In addition, we may initiate claims or
litigation against third parties for infringement or to establish the validity of our proprietary rights, which could be costly and divert the efforts and attention of management, regardless of
whether we are successful. </FONT></P>

<P><FONT SIZE=2><B>The loss of key personnel without adequate replacement could have a material adverse impact on our ability to sustain or grow our business.  </B></FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We believe that our future success significantly depends on our ability to attract, motivate and retain highly qualified management, technical and marketing
personnel. The competition for these individuals is intense. From time to time, there may be a shortage of skilled labor, which may make it more difficult and expensive for us to attract, motivate and
retain qualified employees. We believe our inability to do so could negatively impact our business, financial condition and operating results. </FONT></P>

<P><FONT SIZE=2><B>Our business may be affected by governmental regulation of the telecommunications industry.  </B></FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We are not directly regulated in the U.S., but many of our U.S. customers and the telecommunications industry generally are subject to Federal Communications
Commission regulation. In overseas markets, there are generally similar governmental agencies that regulate our customers. We believe that regulatory changes could have a significant negative effect
on our business and operating results by restricting our customers' development efforts, making current products obsolete or increasing competition. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our
customers must obtain regulatory approvals to operate certain of our products. Any failure or delay by any of our customers to obtain these approvals would adversely impact our
ability to sell our products. The enactment by governments of new laws or regulations or a change in the interpretation of existing regulations could adversely affect the market for our products. The
increasing demand for wireless communications has exerted pressure on regulatory bodies worldwide to adopt new standards for such products, generally following extensive investigation and deliberation
over competing technologies. In the past, the delays inherent in this governmental approval process have caused, and may in the future cause, the cancellation or postponement of the deployment of new
technologies. These delays could have a material adverse effect on our business, results of operations and financial condition. </FONT></P>

<P><FONT SIZE=2><B>Risks related to Arthur Andersen LLP  </B></FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Arthur Andersen LLP audited Celiant Corporation's financial statements for the period from March&nbsp;9, 2001 through September&nbsp;30, 2001 included in our
Form&nbsp;8-K/A filed on August&nbsp;6, 2002 and incorporated by reference in this prospectus. Because Celiant's former engagement team leaders have since left Andersen, Andersen did
not reissue its report on those financial statements, and a copy of a previously issued report was included in the Form&nbsp;8-K/A. Andersen was convicted on June&nbsp;15, 2002 of
federal obstruction of justice arising from the government's investigation of Enron Corp. You may have no effective remedy against Andersen in connection with a material misstatement or omission in
these financial statements, particularly in the event that Andersen ceases to exist or becomes insolvent as a result of the conviction or other proceedings against Andersen. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Until
our consolidated audited financial statements for the fiscal year ending September&nbsp;30, 2003 become available during our first fiscal quarter of 2004, the SEC's current rules
would require us to present or incorporate by reference audited financial statements of Celiant for the period Celiant was audited by Andersen. Prior to that time the SEC may cease accepting financial
statements audited by Andersen, in which case we would be unable to access the public capital markets unless Ernst&nbsp;&amp; Young LLP, our current independent accounting firm, or another independent
accounting firm, is able to audit the financial statements originally audited by Andersen. Following the conviction of Andersen, the SEC issued a release stating that Andersen has informed the SEC
that it will cease practicing before the SEC by August&nbsp;31, 2002, unless the SEC determines another date is appropriate. Although the SEC has indicated that in the interim it will continue to
accept financial statements audited by Andersen, there is no assurance that the SEC will continue to do so in the future. If the SEC declines to accept </FONT></P>
