Exhibit A Non‐Routine Earth Station Antenna, Uplink EIRP Density, and Protection from Interference In this application, GCI Communication Corp (GCI) proposes to employ the two Ku‐band earth station antennas that have been recognized as non‐compliant with the antenna performance standards defined in 47 C.F.R. Ch. 1 §25.209. Per the instructions set forth in the FCC International Bureau Public Notice DA 09‐425 (“International Bureau Establishes Website For List Of Previously Approved Non‐Routine Earth Station Antennas”), GCI cites the following non‐routine earth station applications to serve as a reference for these non‐compliant antennas that are listed in this GCI application: Antenna Manufacturer / Size #1: Prodelin / 0.95m Antenna Model Number #1: 1951 Reference Application File Number #1: SES‐MOD‐20060321‐00478 Reference Call Sign #1: E000658 Reference Licensee Name #1: MCI Communication Services, Inc. Antenna Manufacturer #2: Norsat / 1.0m Antenna Model Number #2: Newslink 3200 Reference Application File Number #2: SES‐LIC‐20060119‐00068 Reference Call Sign #2: E060015 Reference Licensee Name #2: Alaska Broadcasting Company Inc. As presented in the FCC license associated with Call Sign E000658 (noted above), GCI will operate the 0.95m earth station associated with its’ application (Prodelin 1951) at a level 9.2 dB below the maximum power density into the antenna defined in 47 C.F.R. Ch. 1 §25.212(c). As such, the maximum EIRP density will not exceed ‐23.2 dBW/4kHz (calculated as: ‐14.0 dBW/4kHz – 9.2 dB = ‐23.2 dBW/4kHz). As presented in the FCC license associated with Call Sign E060015 (noted above), GCI will operate the 1.0m earth station associated with its’ application (Norsat 3200) at a level 8.7 dB below the maximum power density into the antenna defined in 47 C.F.R. Ch. 1 §25.212(c). As such, the maximum EIRP density will not exceed ‐22.7 dBW/4kHz (calculated as: ‐14.0 dBW/4kHz – 8.7 dB = ‐22.7 dBW/4kHz). Furthermore, GCI understands that it is not protected from interference which may result from the aforementioned antennas main lobe and/or side lobe performance characteristics. As such, GCI will only seek protection to the level associated with an antenna meeting the performance standards defined in 47 C.F.R. Ch. 1 §25.209.
