Standard Configurations: Antenna 2-15
Install the antenna according to the instructions in the manual supplied with the antenna. Do not
route the RF cable alongside the control cable. This will help prevent transmissions from interfering
with the radio’s microprocessors. In addition, do not tightly coil any excess cable inside your vehicle,
as this may interfere with RF transmissions.
Observe the following recommended minimum antenna spacing for in-band radios:

2.5.1 Mini-UHF 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
loosen. Using a tool (pliers or wrench) will not overcome a poor engagement, and is not
recommended.
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).
The mini-UHF connector tool (Motorola part number HLN6695_) is designed to securely tighten the
antenna plug–radio jack connection without damaging either the plug or the jack.
Motorola recommends the following sequence to ensure proper attachment of the system (see
Figure 2-23):
Figure 2-23. Mini-UHF Connection
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. Make sure that the mini-UHF jack is tight in the radio housing.
4. 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.
5. 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.
