3.5.3 Antenna Connection

To ensure a secure connection of an antenna cable's mini-UHF plug to a radio's mini-UHF jack, their
interlocking features must be properly engaged. If they are not properly engaged, the system will loos-
en.
NOTE: Applying excessive force with a tool can cause damage to the antenna or the connector (e.g.,
stripping threads, deforming the collar or connector, or causing the connector to twist in the
housing opening and break).
Vertex Standard recommends the following sequence to ensure proper attachment of the system (see
Figure 3-10):
1. Make sure that there is sufficient slack in the antenna cable.
2. Make sure that the collar of the antenna cable plug is loose and does not bind.
3. Slide the collar back against the flange. Insert the antenna cable plug's pin fully into the radio jack,
but do not engage the threads.
4. Ensure that the plug's and jack's interlocking features are fully seated. Check this by grasping the
crimp on the cable jack, rotating the cable, and noting any movement. If the features are seated
correctly, there should be NO movement.
5. Finger-tighten the antenna cable plug's collar onto the radio's jack.
6. Give a final tug, by hand, to the collar, and retighten by hand as firmly as possible.
7. Use the rubber-coated pliers to grip the plug's knurled collar, then turn clockwise to tighten the col-
lar. It should take 1/4 turn or less. Turning counterclockwise loosens the collar.
NOTE: Overtightening the collar can damage the connector and the radio.
