GNSS Antenna Installation
3. Wrap the connectors with weatherproof tape for added protection.
4.
Verify that the antenna coaxial cable center conductor is not shorted to the shield of
the cable
.
Connecting the GNSS Antenna
You should install the antenna cable from the lightning arrestor to the TimeProvider
2700 using the shortest route possible. Follow all applicable building and electrical
codes to ensure a water-tight and fire-resistant installation.
To connect the GNSS antenna, perform the following steps:
1. Using a DVM, 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
lightning arrestor. Therefore, apply the same measurements directly to the GNSS
antenna. This requires disconnecting the antenna cable at the antenna.
2. Secure the free end of the antenna cable to the SMA (f) antenna connector on
the front panel of the TP 2700.
Antenna Installation Completeness Checklist
To verify that antenna installation is complete:
Verify that all power and ground wires are installed correctly and securely
fastened.
Verify that all input and output cables are properly installed.
Verify that all antenna connectors are secure, tight, and weatherproofed.
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.
Recommendation: Symmetricom recommends coiling excess cable
to avoid gain mismatch between the GNSS antenna and the TP 2700.
Coiling the excess cable also allows you to use the factory-installed
crimped connector.
