August 1. 2002 FCC Experimental Radio Services P.0O. Box 358320 Pittsburgh, PA 1525 1—5320 Dear Sir: My company, VertexRSI, is planning to conduct antenna testing on a special C—band 4.8m satellite antenna at our facility in Kilgore, Texas on or about August 20of 2002. We have conducted a frequency coordination, via Comsearch, (see attached) and have filled with the FCC for a experiential license for this station to operate. In order to ensure that the station is licensed in time to meet our testing schedule we are submitting a STA request (form 159—C is attached). The license is for VertexRSI, 2600 N. Longview Street, Kilgore , TX 75622. The antenna will be a special modified version of our 4.8m C—band high wind design with a 4—port circular feed in a fixed configuration. The testing will consist of antenna transmit and receive patterns, G/T measurement, Intelsat SSOG carrier line—up tests on the Intelsat 903 satellite. The testing is scheduled to begin on 8/21and complete on 8/30 and will likely be conducted from 8 AM till 5PM Central Time. The station will be equipped with 2.2 kW Klystron amplifiers in a redundant configuration, redundant Newtec modulators and upconverters, redundant LNAs and block down converters. The stations will be conducting the tests on transponder 38, 6382—6423 MHz on the Intelsat 903 satellite located at 325 degree East. For the antenna testing a low power CW carrier will be used. For the carrier line—up a digital video carrier will be transmitted with an EIRP of no more than 59.6 dBW/MHz. I trust that this application will be received favorably and that we will be receiving our STA prior to August Sincerely, C/Zx William C. Powell Program Manager VertexRSI 770—689—2044 enclosures
