2.1.3.1 Required Antenna for the GIA 63
Antennas used with the GIA 63 (non-WAAS) must meet the antenna specifications shown in Section 2.6.
In addition, TSO-C144 antennas can also meet TSO-C129a requirements for the GIA 63 (non-WAAS) if
their additional gain (which is about 16dB at 1.5 GHz for antennas produced by Garmin) is offset by added
attenuation in-line with the GIA 63 (non-WAAS). If an in-line attenuator is used, it must pass DC current
(40 mA max at 4.6 VDC) which is provided from the GPS receiver to the antenna pre-amplifier.
2.1.3.2 Required WAAS Antennas for the GIA 63W and GIA 63H
The following is a list of TSO-C144 antennas that allow the GIA 63W and GIA 63H with GPS software
version 3.2 or later to meet TSO-C145a requirements without requiring the operational limitations
specified in Section 1.6.10.2 of this manual:
