Box 7018 Bedminster, NJ 07821 Office (908)—470—2326 Fax (908)—470—2546 January 6, 2003 | Ms. Sylvia Lam ® Federal Communications Commission Satellite and Radiocommunication Division International Bureau The Portals, Room 7—A346 445 12th Street, S.W. Washington, DC 20554 Subject: STA request for Mobile Satellite Connection to transmit using a 2.4 meter C—band temporary—fixed earth station from Honolulu, Maui, and Kona Hawaii to the Telstar 7 Satellite located at 129° West Longitude. Dear Ms. Lam: The purpose of this letter is to certify that Loral Skynet®‘ is fully aware that Mobile Satellite Connection is planning to communicate with the Telstar 7 U.S. domestic satellite using Prodelin offset C—band transmit/receive antennas that do not strictly conform to the FCC 2— degres spacing requirements for off—axis sidelobe gain*. Loral Skynet is authorized to operate and currently operates Telstar 7 at 129°,WL in the geostationary earth orbit. The undersigned certifies that Loral Skynet has examined the performance parameters of the Prodelin 2.4 meter diameter antenna, as it is to be used by Mobile Satellite Connection. This antenna exhibits non—conformance in the region from 1.0 to 1.5 degrees off axis from maximum gain, due to the width of its main gain lobs. It is understood that this antenna will be used to transmit wideband digita) carriers, typically having a symbol—rate bandwidth of 20 MHz and operating at a maximum input power density at the antenna waveguide flange of ——16.0 dBW/4 kHz. \ Skynet is a registered trademark of Loral SpaceCom Corporation *4?7 CFR § 25.209

91/205—2003 14:58 LORAL SKYNET > 917037265593 i+ NO.641 Das “f Loral Skynet confirms that the operation of this antenna with these parameters is fully consxstefit with the Telstar 7 coordination agreements, and will be taken into account as necessary in all future intersystem coordination agreements between Loral Skynet and affected adjacent satellite operators. Respectfully, Robert C. Draper
