Maintain approximately 5 feet from fluorescent lamps, related ballast, air conditioners, blowers, strobe lights, and power supplies. 2. The minimum distances to be observed when selecting an antenna location are as follows: • 1.5 inches from any passive (receive only) antenna such as GPS, XM, or another Wi-Fi. • 20 cm is maintained between the antenna and all persons in the aircraft. • 5 inches from a VHF active antenna such as COM or ACARS. • 5 inches from an active radar altimeter (4 GHz). • 12 inches from a UHF/Microwave transmitting antenna such as a transponder, DME, active TCAS, UAT, SATCOM, or Flitephone. 3.3.4 Wi-Fi Antenna to Receiver Signal Requirements Observe the following antenna requirements: (1) Wi-Fi antenna maximum gain is 5 dB. (2) Wi-Fi antenna must be omni-directional. (3) The interconnect and antenna gain/loss component must be between +6dB and -4dB. If the interconnect and antenna gain/loss component is outside this range, additional gain or loss must be added between the antenna and the GDL 59 RF input. (4) Antenna input cannot exceed Maximum Power Input levels listed in Section 1.4.3. GDL 59 Installation Manual 190-00837-00 Page 3-3 Revision C
