Follow these steps to connect the antenna cable to the
BDU.
1. Clean and dry the “Antenna” TNC connector on the
BDU.
2. Fill half of the inner body of the antenna cable’s male
TNC connector with the supplied silicone grease.
3. Connect and SLOWLY hand-tighten the cable to the
BDU connector, allowing the grease to diffuse and
settle into the entire space within the connector. Do
not use a tool or overtighten.
4. Secure the antenna cable to the strain-relief bracket.
Also make sure the cable will not get bent or twisted
near the BDU’s connection, which can put additional
stress on the connector.

IMPORTANT!
If you are using an RG-58 or LMR-240 cable, you may
connect it directly to the BDU. If you are using any
other type of cable, you must connect a pigtail cable
between it and the BDU. See “Connecting Pigtail
Cables to the Antenna Cable” on page 36.
IMPORTANT!
Do not connect anything other than the antenna cable
to the “Antenna” connector. The BDU supplies voltage
that will damage other devices.
