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 General Dynamics 2244 2.4m C-band earth station antenna. This antenna is, in terms of performance, identical to the General Dynamics (formerly Prodelin) 1244 antenna. The General Dynamics 2244 antenna has been recognized as non-compliant with the antenna performance standards defined in 47 C.F.R. Ch. 1 §25.209. Included as part of this exhibit are three documents from General Dynamics namely (a) a letter affirming that the 2244 antenna does indeed have the same technical performance characteristics as the Prodelin 1244 antenna and (b) the manufacturer data sheets for each antenna model. 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: Prodelin Corporation Antenna Model Number: 1244 Reference Application File Number: S-LIC-20080718-00955 Reference Call Sign: E080172 Reference Licensee Name: Intelsat LLC As presented in the FCC license associated with Call Sign E080172 (noted above), GCI will operate the earth station associated with its’ application at a level 6 dB 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 General Dynamics 2244 antenna’s 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.

GENERAL DYNAMICS SATCOM Technologies July 29, 2013 Paloma Field General Communication, Inc 2550 Denali Street Suite 1000 Anchorage, Alaska 99503 Re: General Dynamics SATCOM Technologies Model 2244 C—band Tx/Rx Antenna System Ms. Field: This letter is in response to your recent inquiry into the General Dynamics SATCOM Technologies Model 2244 C—band Lincar Tx/Rx Antenna Systemand its performance in relation to the Prodelin Model 1244 C—band Antenna System. As you are aware, the Prodelin antenna brand was acquired by General Dynamics in 2004 as part of the purchase of TriPoint Global Communications. At the time of purchase, the Prodelin brand was a well— known manufacturer of satellite antennas including the Model 1244. After acquiring the Prodelin brand and products, General Dynamics developed the Model 2244 Antenna System which is designed for high—wind operation. However, the operational frequency range, gain, pattern beamwidth and noise temperature are all identical, For all intents and purposes, the performance ofthese two models is identical save for tolerance for high—wind operation. I understand that you are in the process oflicensing the General Dynamics 2244 antenna with the Federal Communications Commission (FCC). For the purposes ofthis licensing effort, the technical performance characteristics of the Model 2244 antenna are the same as the Prodelin Model 1244 antenna. incerely, MQQV?Y@V\%@”\ Penny Stevenson VSAT Sales Manager General Dynamics SATCOM Technologies, Inc. 1500 Prodclin Drive Newton, NC 28658 1500 Prodelin Drive Newton, NC 28658 (P) 828—464—4141 www.gdsatcom.com
