GIA 63H and GIA 63W (011-01105-0X/-2X/-3X) shall meet TSO-C144 and
additional
system
requirements specified by TSO-C145a. Refer to Section 2.1.3.2 for
approved
antennas
GIA 63W (011-01105-4X) shall meet TSO-C144 and additional system requirements
specified by TSO-C145c. Refer to Section 2.1.3.2 for approved antennas
VOR/LOC Antenna:
Shall meet TSO-C40() and C36(). Broad band, 50
Ω
, horizontally polarized
with
coaxial
cable
Glideslope Antenna:
Shall meet TSO-C34(). Broad band, 50
Ω
, horizontally polarized with coaxial
cable or low-loss splitter used with the VOR/LOC antenna
Headphones: 500
Ω
nominal impedance Microphone: Low impedance, carbon or dynamic,
with transistorized pre-amp
Hardware:
#6-32 x 100°Flathead SS Screw [(MS24693, AN507R or other approved
fastener) (4 ea.)] for horizontal mounting of the standalone rack.
Hardware:
#8-32 Panhead Machine Screw [(MS35206, AN526 or other approved
fastener) (4 ea.)] for vertical mounting of the standalone rack.
Hardware:
#10-32 x 100°Flathead Screw [(MS24694S51 or screw of same or greater strength)(4
ea.)] for mounting of the helicopter rack.
*GIA 63W and GIA 63H only
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:
