& LEVENTHAL SENTER & LERMAN PLLC December 10, 2007 Davib S. Ker E—MAIL (202) 416—6742 DKEIR@LSL—LAW.COM BY HAND Marlene H. Dortch, Secretary Federal Communications Commission Office of the Secretary 445 12th Street, SW, Room TW—B204 Washington, DC 20554 Re: Application of Row 44, LLC — SES—STA—20071121—01610 Dear Ms. Dortch: Transmitted herewith on behalf of Row 44, LLC ("Row 44") is additional information which supplements its pending request for Special Temporary Authority ("STA") in the above— referenced file. This information is submitted in response to a November 28 request from Scott Kotler and Jeanette Spriggs of the Satellite Division‘s Systems Analysis Branch for additional technical information demonstrating the compliance of the proposed STA facility with Sections 25.209 and 25.212(c) of the Commission‘s Rules. 47 C.F.R. §§ 25.209 & 25.212(c). In particular, the following information is provided —— (1) additional antenna patterns detailing both the sidelobe emissions of the proposed remote test antenna in the azimuth plane, plus and minus seven degrees, and the cross—polarization pattern, plus and minus nine degrees, which collectively demonstrate that the proposed operation will comply with the requirements of Section 25.209; and (2) revised Schedule B to Form 312 specifying modified power characteristics that comply fully with Section 25.212(c). The transmit antenna gain, total input power at the antenna flange, bandwidth, emission designator, and EIRP parameters for the proposed operation have been modified. The changed parameters are highlighted in the attached Revised Schedule B. Row 44 notes that the test facility will operate using vertical polarization only in the transmit (uplink) mode and with horizontal polarization only in the receive (downlink) mode.

& Ms. Marlene Dortch December 10, 2007 Page —2— indicated in the initial application, the STA facility will operate exclusively with Intelsat‘s Galaxy 10—R satellite at 123° W.L. using a Hub station at Germantown, Maryland previously licensed to Hughes Network Systems, LLC. The frequencies to be utilized for this test will be as follows: (1) 14229.72 MHz, (2) 14230.08 MHz, (3) 14230.44 MHz, and (4) 14230.80 MHz. Should there be any questions about this information, or if additional information is required, please contact the undersigned counsel. ully submitted, * David S.
