                             DESCRIPTION OF EXPERIMENT


Comtech Systems, Inc. ("Comtech") hereby requests FCC experimental Special Temporary
Authority (“STA”) to conduct experimental testing utilizing its Modular Transportable
Transmission System ("MTTS").

The proposed testing involves the use of two troposcatter units, one installed locally and second
installed at a remote site. Each unit will transmit and receive a continuous wave that bounces off
of the troposphere. This method of propagation uses the tropospheric scatter phenomenon,
where radio waves at particular frequencies are randomly scattered as they pass through the
upper layers of the troposphere. Radio signals are transmitted in a tight beam aimed at the
troposphere, midway between the transmitter and receiver sites. As the signals pass through the
troposphere they are scattered, allowing the receiver station to pick up the signal. The
experimental data to be collected include characterization of tropospheric fading, changes in
refractivity versus seasonal climactic changes, measuring aperture coupling losses and
characterizing overall system performance.

Comtech acknowledges that all testing conducted under this experimental authorization will be
on a non-interference basis. Further, Comtech will coordinate frequency usage pursuant to any
directives issued by the Commission on the experimental authorization.

Because the equipment is technically incapable of providing station identification, Comtech
respectfully requests a waiver of the station identification provisions of Section 5.115 of the
Commission's rules, 47 C.F.R. § 5.115.

The stop buzzer contact for this experiment is Paul Kelly at Comtech, tel: (407) 854-1950 ext.
3050, mobile: (321) 948-4315, e-mail: paul.kelly@comtechsystems.com.

Comtech submits that a grant of this application is necessary and in the public interest because it
will facilitate advancements in communications equipment used by the US Military abroad.
