Antenna Installation
4. Connect the ground wire between the transient eliminator and the proper
grounding zone (building ground, master ground bar, or other) for the mounting
location.
5. Wrap the connectors with weatherproof tape for added protection.
6.
Verify that the antenna coaxial cable center conductor is not shorted to the shield of
the cable
.
Installing the Antenna Cable
You should install the antenna cable from the transient eliminator to the
TimeProvider 5000 using the shortest route possible. Follow all applicable building
and electrical codes to ensure a water-tight and fire-resistant installation. .
Connecting the GPS Antenna
Before connecting the GPS antenna to the TimeProvider 5000, see Antenna
Connection Overview, on page 473. Then, follow the instructions below.
1. Verify that the center conductor is not shorted to the shield.
If the reading shows a short or open, you may have a shorted or open cable or
transient eliminator (if installed). Therefore, apply the same measurements
directly to the GPS antenna. This requires disconnecting the antenna cable at the
antenna.
Recommendation: Symmetricom does not recommend soldered
connections for grounding purposes. All grounding connections
should be secured with mechanical clamp connectors.
Caution: To avoid damage to the connectors, do not use the
connectors to pull the cable. If at all possible, avoid bundling the
cable with other cables (and possible noise sources). Use appropriate
cable-pulling devices when pulling the cable through conduit or a
weather head.
Note: The open-circuit range of an individual ohmmeter can cause
readings to vary among meters.
