16.6 Unit Installation
Fabrication of a wiring harness is required. Sound mechanical and electrical methods and practices are
recommended for installation of the GPS 20A. Refer to
Section 25.11
for pinouts.
1. Mount the unit to a suitable mounting location using (4) #10-32 pan or hex head screws.
2. Assemble the connector backshells and wiring harness.
3. Connect CAN terminator to unit if required
4. Connect backshell connectors.
16.7 Antennas
The GPS 20A requires the installation and use of a GA 35, GA 36, GA 37, or equivalent GPS/WAAS
antenna. Refer to
Section 22
16.8 Antenna Cable Requirements
Cable loss from the GPS/SBAS antenna should be between 1.5 dB and 6.5 dB in order to maintain proper
rejection to interference signals.
Coaxial connectors and adapters, such as TNC to BNC, add additional loss to the cable and should be
considered when computing the cable loss. A typical loss of 0.2 dB can be used for each connection.
For RG-142B or RG-400, 1.5 dB equates to a length of approximately 6.5 feet of cable with a connector on
each end.
For installations that require less than 6.5 ft of cable, the cable may be coiled, taking into account the
minimum bend radius of the cable.
