IBFS File No. SAT-STA-20061207-00145 IBFS File No. SAT-STA-200707 19-00104 IBFS File No. SAT-STA-20070928-00135 IBFS File No. SAT-STA-200712 13-00174 Dear Ms. Dortch: Sirius Satellite Radio Inc. (“Sirius’’) hereby files this letter providing updated information related to its Special Temporary Authority’ to operate terrestrial repeaters at the sites approved on the above-captioned applications. Specifically, Sirius provides updated information regarding the antennas to be used in connection with the terrestrial repeaters at these sites. In 2006, prior to the construction of the sites listed on these applications, Andrew Corporation acquired EMS Wireless, Sirius’s original antenna supplier. Subsequently, Andrew discontinued the antenna models listed on the above-referenced applications and replaced them with two new models. A letter from Andrew Corporation detailing this discontinuance is attached as Exhibit A. Because of this discontinuance, Sirius plans to deploy the two Andrew units in lieu of the original EMS antenna models at all of the sites listed on the affected applications. For the Commission’s convenience, Sirius has provided a list of the affected sites as Exhibit B. Sirius emphasizes that the change in antenna models will have no effect on the other technical parameters listed in the subject applications, including repeater power, downtilt, sectorization, antenna height, and 1 There are pending requests for renewal in connection with three of these application. IBFS File No. SAT-STA-2007 1220-00 179 seeks to renew SAT-STA-2006 1207-00 145, IBFS File No. SAT-STA-200803 14-0007 1 seeks to renew SAT-STA-200707 19-00104, and IBFS File No. SAT- STA-20080530-00116 seeks to renew IBFS File No. SAT-STA-20070928-00 135. Sirius will also seek renewal of the other application affected prior to the expiration of its 180-day term.

June 4,2008 Page 2 location. In addition, as noted in the attached technical comparison, Exhibit C, the Andrew models are substantially similar to their EMS predecessors and will present no additional potential for interference. Should you have any questions regarding this filing, please contact the undersigned. Sincerely, Carl R. Frank Counsel to Sirius Satellite Radio Cc: Roderick Porter Stephen Dual1 I
