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 Patriot Antenna Systems TXINT‐380AZ 3.8m C‐band earth station antenna which has 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 application to serve as a reference for this GCI application: Antenna Manufacturer: Patriot Antenna Systems Antenna Model Number: TXINT‐380 Reference Application File Number: S‐LIC‐20061115‐02001 Reference Call Sign: E060415 Reference Licensee Name: WITF, Inc As presented in the FCC license associated with Call Sign E060415 (noted above), GCI will operate the earth station associated with its’ application at a level 6dB below the maximum power density into the antenna defined in 47 C.F.R. Ch. 1 §25.212(d)(2). As such, the maximum EIRP density will not exceed ‐8.7 dBW/4kHz (calculated as: ‐2.7 dBW/4kHz – 6.0 dB = ‐8.7 dBW/4kHz). Furthermore, GCI understands that it is not protected from interference which may result from the Patriot Antenna Systems TXINT‐380 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.
