190-00303-05 GIA 63 Installation ManualRev. Y Page 2-32.1.3 Additional Equipment RequiredThe following installation accessories are required but not provided:COM Antenna: Shall meet TSO-C169()*, or shall meet both TSO-C37() and C38(),Broad band, 50 Ω, vertically polarized with coaxial cableGPS Antenna: GIA 63 (011-00781-0X) shall meet TSO-C129a. TSO-C144 antennas can alsomeet TSO-C129a requirements for the GIA 63 (Refer to Section 2.1.3.1).GIA 63H and GIA 63W (011-01105-0X/-2X/-3X) shall meet TSO-C144 andadditional system requirements specified by TSO-C145a. Refer to Section 2.1.3.2 forapproved antennasGIA 63W (011-01105-4X) shall meet TSO-C144 and additional system requirementsspecified by TSO-C145c. Refer to Section 2.1.3.2 for approved antennasVOR/LOC Antenna: Shall meet TSO-C40() and C36(). Broad band, 50 Ω, horizontally polarizedwith coaxial cableGlideslope Antenna: Shall meet TSO-C34(). Broad band, 50 Ω, horizontally polarized with coaxialcable or low-loss splitter used with the VOR/LOC antennaHeadphones: 500 Ω nominal impedance Microphone: Low impedance, carbon or dynamic,with transistorized pre-ampHardware: #6-32 x 100°Flathead SS Screw [(MS24693, AN507R or other approvedfastener) (4 ea.)] for horizontal mounting of the standalone rack.Hardware: #8-32 Panhead Machine Screw [(MS35206, AN526 or other approvedfastener) (4 ea.)] for vertical mounting of the standalone rack.Hardware: #10-32 x 100°Flathead Screw [(MS24694S51 or screw of same or greater strength)(4ea.)] for mounting of the helicopter rack.*GIA 63W and GIA 63H only2.1.3.1 Required Antenna for the GIA 63Antennas 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) iftheir additional gain (which is about 16dB at 1.5 GHz for antennas produced by Garmin) is offset by addedattenuation 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 63HThe following is a list of TSO-C144 antennas that allow the GIA 63W and GIA 63H with GPS softwareversion 3.2 or later to meet TSO-C145a requirements without requiring the operational limitationsspecified in Section 1.6.10.2 of this manual:
