4. Mounting restrictions for certain radio models
For 40 Watt UHF models and all 110W models, the 1/4 wave antenna should be mounted
only in the center area of the roof, not on the trunk lid, to assure compliance with RF
Energy Safety standards.
5. Ensure that the antenna cable can be easily routed to the radio. Route the antenna cable as
far away as possible from any vehicle electronic control units and associated wiring.
6. Check the antenna location for any electrical interference.
7. Ensure that any other mobile radio antenna on this vehicle is at least one foot (30.48 cm)
away from this antenna.
NOTE: Any two metal pieces rubbing against each other (such as seat springs, shift levers,
trunk and hood lids, exhaust pipes, etc.) in close proximity to the antenna can cause
severe receiver interference.

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
