2-40 Standard Configurations Antenna Installation
2.4.2 Mini-UHF Connection
To help aid in the installation of the radio antenna(s), there are labels indicating the frequency. The
first is on the FCC label at the top of the radio which calls out the frequency and by using arrow
points, which side the RF connector of the frequency is located at the back of the radio. The second
is located at the back of the radio, next to the RF connector(s) (see Figure 2-50). 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 2-50 and Figure 2-51):
Figure 2-50. Mini-UHF Connection (As Shown on Mid Power)
Figure 2-51. Mini-UHF Connection (100W Radios Only)
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.
