Affidavits from Adjacent Satellite Operators Attached are the affidavits from the adjacent satellite operators demonstrating that the 0.75 meter antennas will operate satisfactory with all adjacentsatellites. The applicant agrees to accept any adjacent satellite interference in the 12 GHz receive band as a result of the performanceof the antenna in the 1° to 1.5° region. The applicant understands that no adjacent satellite interference protection will be available in the 1° to 1.5° regions. The applicant understands that adjacent satellite interference protection applies only to the extent of the criteria set forth in §25.209.

10 March 2010 @ INTELSAT Federal Communications Commission International Bureau 445 12"" Street, S.W,. Washington, D.C. 20554 To whomn it may concern: This letter certifies that Intelsat is aware that Spacenet Services License Sub, Inc. ("Spacenet") is seeking FCC authorization to access the Galaxy—18 satellite at 123.0° W.L. as a point of communication, using Ku—band transmit/receive antennas that are not strictly compliant with the FCC 2— degree spacing requirements for off—axis sidelobe gain.‘ intelsat understands that Spacenet will be deploying transmit/receive earth station antennas of 62.x 89 cm, using an Andrew Model 755 antenna, mounted in all cases such that the major axis of the ellfiptical reflector is aligned with the geostationary orbit arc. The above antenna is not compliant with Section 25.209 of the FCC rules insofar as the antenna meets the sidetobe performance only at an angle of 1.72 degrees and greater, rather than 1.5 degrees and greater as specified in the FCC rules. These antennas are to be operated with a pointing error that will not exceed £0.3° and will operate at a maximum input power density at the antenna waveguide flange of —15 dBW/4 kHz, which is 1 dB fower than the limit contained in 47 CFR §25.134. intelsat and Spacenet further certify that the maximum forward downlink satellite EIRP density is equal to or less than +13.0 dBW/AKHz, which is routinely used at 2—degree spacing without causing unacceptable interference to adjacent satellite operators. Furthermore, in order to prevent unacceptable interference into adjacent satellites, Intelsat has been informed and Spacenet acknowledges that these antennas will be installed in compliance with the technical, operational and performance requirements of Part 25 of the FCC rules and any requirements set forth in the licenses granted by the FCC for the above antennas. Intelsat and Spacenet acknowledge that they will not seek any additional protection compared to the case of an earth station employing an antenna conforming to the reference patterns defined in § 25.209 of the FCC rules. ‘ 47 CFR §25.209.

Intelsat acknowledges that the use of the above referenced transmit/receive antenna by Spacenet, installed and operated in accordance with the above conditions should not cause unacceptable interference into adjacent satellites aperating in accordance with FCC‘s 2—degree spacing policy. Spacenet has agreed that should operation of this antenna cause unacceptable interference into other systems, Spacenet will terminate transmissions immediately upon notice from the affected parties. @ INTELSAT Finally, Intelsat acknowledges that it will include the subject non—conforming earth station operations in all future satellite network coordinations.
