From: Leland [mailto:uplinktruck@14GHz.com] Sent: Tuesday, August 16, 2005 10:48 AM To: Eleanor Lott; Frank Peace Subject: Application File Number SES-LIC-20050801-01010, Call Sign E050235 Sabil Alliances, LLC 15230 Champion Lakes Place Louisville, KY 40245 (502) 253-3416 Federal Communications Commission International Bureau 445 12th Street S.W. Washington, DC 20554 Attn: Eleanor Lott Re: Call Sign E050235, File Number SES-LIC-20050801-01010 Good Morning, We acknowledge and will comply with the 358 Watt maximum power limit when uplinking a digital carrier under this license. This will bring the maximum power density under the -14dBW/4KHz allowed under CFR 25.212. These are the calculations we used to get to this number: Digital constants: Transmit power (P) = 358 watts, Antenna Gain (G) = 49.63 dBi 312-B7f (Maximum EIRP - digital) EIRP = 10LOG (P) + G EIRP = 10LOG (358) + 49.63 EIRP = 75.1688 dBW 312-B7g (Maximum EIRP Density - digital) EIRP Density = EIRP - 10LOG (Transmit Bandwidth) / 4kHz EIRP Density = 75.1688 - 10LOG (36) / 4kHz EIRP Density = 35.6264 dBW/4kHz Maximum Power Density Power Density = EIRP Density - G Power Density = 35.6264 - 49.63 Power Density = -14.0036 dBW/4kHz Thank you for your time and attention to this matter,
