The glareshield-mounted GPS antenna (Garmin part number 011-04036-00) feeds a GPS receiver inside the G5 which provides position, velocity, and time data to support various functions.
If the primary G5 is installed as an ADI, HSI, or DG and not connected to a WAAS enabled GPS source, the G5 must be connected to this antenna.
It is designed for installation on top of an existing instrument panel glareshield. The selected location must offer good visibility of the sky through the windshield. Installation of the GPS antenna cannot obstruct or limit the pilotís vision (even though the antenna has a low profile). The optimal antenna position is horizontal, or as close to horizontal as practical given the shape of the glareshield.
Fastener holes for screw-mounted antenna installation must not penetrate through the ventilation or defrost channels built into the glareshield, if present. If the glareshield is part of the instrument panel structure, fastener holes may only be drilled if provisioned by the aircraft maintenance manual or structural repair manual.
A TNC/BNC Adaptor (P/N 11-17444) is required to connect the GPS antenna to the G5.
This antenna has a TNC connector. In order to connect to a G5 you will also need p/n: 11-17444.
This antenna cable is approximately 8 ft long.
Unfortunately the STC for the G5 does not provide an alternative antenna.
No it is not a WAAS GPS antenna.
It is not required as the unit has a built-in receiver/antenna. However it is recommended to use one for a secure signal.
