Mini-UHF Connection
Note: 1. The RF connector (J3) on APX VA console is a mini-UHF jack, and
must be mated with either an antenna mini-UHF plug (P3) or an
appropriate adapter (part numbers: 5880367B21 [mini-UHF-to-N];
5880367B22 [mini-UHF-to-UHF]; or 5880367B24 [mini-UHF-to-
TNC]).
To ensure a secure connection of an antenna cable's mini-UHF plug
to an APX VA 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.
2. Applying excessive force with a tool can cause damage to the
antenna or the connector (such as stripping threads, deforming the
collar or connector, or causing the connector to twist in the housing
opening and break).
The mini-UHF connector tool (part number HLN6695) is designed to
securely tighten the antenna plug-APX VA jack connection without
damaging either the plug or the jack.
Motorola recommends the following sequence to ensure proper attachment of
the system (see Figure 6).
Collar Pulled Back
to Flange
Flange
1. Ensure that there is sufficient slack in the antenna cable.
2. Ensure that the collar of the antenna cable plug is loose and does not
bind.
3. Ensure that the mini-UHF jack is tight in the APX VA housing.
4. Slide the collar back against the flange. Insert the antenna cable plug's
pin fully into the APX VA jack, but do not engage the threads.
