GNSS Antenna Installation
Connecting the Cable to the Antenna
This section describes how to connect the coaxial cable to the mounted antenna.
Refer to
for the numbered references in the following procedure.
1. If an in-line amplifier is not required:
– Connect the TNC-N adapter (#5) to the antenna (#1).
– Connect the 10 m cable (#6) to the TNC-N adapter (#5).
2. If an in-line amplifier is required:
– Connect TNC-TNC adapter (#3) to the antenna (#1).
– Connect the in-line amplifier (#4) to the TNC-TNC adapter (#3).
– Connect the TNC-N adapter (#5) to the In-line amplifier (#4.)
– Connect the 10 m cable (#6) to the TNC-N adapter (#5)
.
3. Connect the other end of the 10 m cable (#6) to the lightning arrestor (#7).
4. Connect the lightning arrestor (#7) to the long cable (#8).
5. Connect the other end of the long cable (#8) with the cable adapter (#9).
Installing the Lightning Arrestor
Lightning arrestors should be installed in accordance with your antenna system
grounding scheme. To install a lightning arrestor, follow these steps:
1. Mount the lightning arrestor within 30 ft. (9 m) of the GNSS antenna.
2. Connect the ground wire between the lightning arrestor and the proper grounding
zone (building ground, master ground bar, or other) for the mounting location.
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.
Caution:
To avoid damage to internal solder connections, do not
over-tighten the connector.
Recommendation:
Symmetricom does not recommend soldered
connections for grounding purposes. All grounding connections
should be secured with mechanical clamp connectors.
