Intelsat. inspiring connections 10 May 2005 Federal Communications Commission International Bureau 445 12th Street, SW Washington, D.C. 20554 To Whom It May Concern: This letter certifies that Intelsat is aware that Globecomm Systems, Inc. ("Globecomm"), is filing to operate on Intelsat Americas 6 at 93° W.L , licensed by the Federal Communications Commission ("FCC"), using a Ku—band transmit/receive antenna that is not strictly compliant with the FCC rules for off—axis sidelobe gain.‘ The Ku—band terminal will use one AvL Model 9066, temporary fixed antenna with a dimension of 90 x 66 cm (an equivalent aperture of 0.75 meter). Intelsat understands that this antenna generally exhibits non—compliance performance in the region from 1.0 to 1.73 degrees off axis from the maximum gain. The antenna complies at 1.73 degrees and beyond with the requirements of Section 25.209 of the FCC‘s rules. In order to prevent potential unacceptable interference from antenna misalignment, Globecomm will align the 90x66 cm antenna to less than or equal to 0.27 degrees offset in the azimuth direction of the intended satellite and the 90—cm dimension will be tangent to the GSO—arc. In addition, the uplink power density for the antenna used by Globecomm and operating on the Intelsat Americas 6 at 93° W.L will not exceed —14.0 dBW/4 kHz into the antenna flange. Intelsat acknowledges that the use of the AvL Model 9066 antenna by Globecomm, installed and operated in accordance with the above conditions, should not cause unacceptable interference into adjacent satellites in accordance with FCC‘s 2—degree spacing policy and that Globecomm will not seek any additional protection compared to the case of an antenna conforming to the reference patterns defined in Section 25.209 of FCC rules. If the use of this antenna should cause interference into other systems, Globecomm has agreed that it will terminate transmission immediately upon notice from the affected parties.
