Appendix C Installing the GPS Antenna
Antenna Installation
1. Loosen the four screws securing the top of the antenna in place to gain access to the
connector.
2. Route the shorter antenna coaxial cable from the antenna through the floor
flange (in the lower half of the antenna base) to the unit.
Caution: To avoid damage to the connectors, do not use the
connectors to pull the cable. If at all possible, avoid bundling the
coaxial cable with other cables (and possible noise sources). Use
appropriate cable-pulling devices when pulling the coaxial cable
through conduit or a weather head.
3. Connect the cable to the antenna and run the cable from the antenna through the
slot of the floor flange.
Caution: To avoid damage to internal solder connections, do not
over-tighten the connector.
4. Replace the four screws to secure the top of the antenna in place with the cable
connected.

Installing the Transient Eliminator

If you are installing a transient eliminator, follow these guidelines:
Transient eliminators should be installed in accordance with your antenna system

grounding scheme
Mount the transient eliminator within 30 feet (9 m) of the GPS antenna

If required, mount a second transient eliminator near the GPS antenna

To install the transient eliminator:
Note: Step 6 in the following procedure cannot be done if you cut the
cable (as described in Step 1).
1. If necessary, cut the coaxial cable and install mating connectors (see
Antenna Cables, on page 476).
2. Using the DVM, measure the resistance between the center conductor and
shield to verify that the center conductor and shield are not shorted together.
3. Connect the longer GPS antenna coaxial cable to the transient eliminator.
