TracPhone V30 Installation Guide
Wire the Antenna
Follow these steps to connect the coax cable to the
antenna’s power/data baseplate connector.
Route the Cable Belowdecks
1. Route the opposite end of the antenna cable
belowdecks through the 1.5" (3.8 cm) cable access
hole. Leave an adequate service loop, 14" (36 cm) in
diameter, at the antenna location for easy
serviceability.
2. Route the cable to the VSAT-Hub. Be sure to always
maintain the minimum bend radius in the cable. If you
cannot maintain the minimum bend radius, refer to
“Wiring the Antenna Using Pigtail Cables” on page 34 .
Later, you will connect the cable to the VSAT-Hub.

Connect the Cable to the Antenna
1. Clean and dry the antenna cable’s connector and the
power/data connector on the bottom of the baseplate.
Figure 11: Antenna Baseplate Connector
2. Fill half of the inner body of the cable’s male connector
with the supplied silicone grease.
3. Connect and SLOWLY hand-tighten the cable to the
baseplate connector, allowing the grease to diffuse
and settle into the entire space within the connector.
4. Make sure the cable connector is tightened all the way
into the antenna’s connector. Then tighten the
connector with a 5/8" torque wrench set to 23 in.-lbs.
5. Seal the cable connection with silicone sealant or
equivalent.

6. Secure the antenna cable near the antenna connector
to relieve stress.
7. Weatherproof and seal the cable access hole.
