                                      Exhibit 1

a)   The complete program of research and experimentation proposed including
     description of equipment and theory of operation.

     Andrew Corporation is currently in the process of developing a wide variety of
     passive antennas for use in a number of different telecommunications
     applications. The antennas under development include, but are not limited to, a
     comprehensive range of omnidirectional and sectorized antennas incorporating
     state of the art pattern shaping techniques for wireless base station applications
     and which cover a number of different frequency bands of operation. Research
     work is underway into dual slant polarized antennas as used for newer
     applications in wireless communications. The use of dual polarization has been
     shown to reduce the number of antennas mounted on a cellular base station tower,
     thereby improving the aesthetics and reducing the delays associated with the
     zoning and planning process when conventional, larger structures are involved.
     Other advanced antenna developments for which the experimental license is
     required include dual band antennas, where two or more antennas can be placed in
     one package reducing zoning problems, and variable electrical downtilted
     antennas, where a phase shifting system internal to the antenna can be used to
     permit the varying of the electrical downtilt of a sectorized base station antenna.
     This latter feature is of particular use to wireless network operators since it
     enables them to make critical system adjustments in a shorter time, thereby
     reducing cost and improving service to their customers.

     Equipment to be used at Andrew Corporation is based around conventional, but
     state of the art, outdoor far field test range facilities. In order to optimize the
     dynamic range of the systems to allow >40 dB front-to-back ratio measurements,
     the test sites are configured with a directional receiving antenna located close to
     the ground. At a specific distance away from the receiving antenna, there is a
     mounting facility where an antenna under test can be installed and then rotated in
     the principle plane connecting the receiving antenna and the antenna under test.
     A frequency generator is connected to an antenna under test and a receiving
     system is connected to the directional antenna located close to the ground. A
     control system synchronizes the recording of the received signal level as a
     function of rotation angle. A variety of computerized software is used to post-
     process the recorded antenna radiation patterns. Such software permits the
     display of the radiation pattern in a variety of standard formats, overlaying of
     patterns and required specifications, overlaying of patterns together with those
     previously recorded, etc.

b)   The specific objectives to be accomplished

     The objectives of the experimental license are to develop, measure and verify the
     performance of Andrew Corporation’s range of antennas for use in a great number
     of wireless applications. A conventional, yet state of the art, antenna test range


     facility is required in order to conduct advanced experimental development (in
     many cases we have found that no suitable theoretical predictions exist), validate
     antenna performance and demonstrate reliable and repeatable production antenna
     performance to a wide customer base.

c)   How the program of experimentation has a reasonable promise of contribution to
     the development, extension, expansion or utilization of the radio art or is along
     lines not already investigated.

     Andrew Corporation is at the forefront of antenna engineering development and
     manufacturing expertise in the world. Antenna developments within Andrew
     Corporation are present on many fronts that push forward the state of the art. Such
     innovations as Smart, switched-beam arrays can improve both coverage and
     capacity in the network using existing antenna sites. Likewise, development of
     multiband antennas enable fully loaded towers to still be used and increase traffic
     capacity. Development of dual slant polarized antennas will mean reduced
     planning delays for operators enabling the network to offer improved service and
     reduced costs to their users. Development of high performance antennas
     incorporating techniques such as electrical downtilt, upper sidelobe suppression
     and lower null fill improve coverage respectively. These features ultimately
     permit service providers to offer improved performance leading to increased call
     quality together with decreased blockage at reduced cost to their users.
