Operational
limitations in
Section 5.2 of this
manual apply.
[1] It is anticipated that there will be no operational limitations when using the GA 35 antenna in
conjunction with a future version of GPS software. Consequently, it is recommended that the GA 35
antenna be used whenever possible.
[2] Same mounting hole pattern as GA 56, but A-34 antenna has a physically larger footprint.
[3] Early production runs of the A-33 were marked with TSO-C129a. This antenna was requalified to
TSO-C144 with no changes to the antenna. A-33 antennas marked with the TSO-C129a identification
are identical to those marked with TSO-C144.
[4] Same footprint and mounting hole pattern as GA 56.
[5] The GPS/WAAS antenna connector is a BNC type. The XM antenna connector is a TNC type.
[6] Compatible on aircraft equipped with SATCOM.
