To remove a magnetic antenna mount, hold it at the bottom of its base and tilt it at an
angle to release the magnetic attraction force. Do not pull on the mount’s coax cable.
Do not drag the mount across the mounting surface.
6.2.3 Installing All Other Antenna Mounts
For any other type of antenna mount not covered in the previous sections, such as GPS combination
antennas, install the mount in accordance with the installation instructions included with the mount.
6.2.4 Attaching NMO Antenna Elements
1. Clean the top surface of the NMO mount and the surface of the vehicle immediately around the
mount.
2. Place the gasket included with the antenna element (not pictured in Figure 6-4 or Figure 6-5) around
the mount and against the surface of the vehicle. If a lubricant or sealant was included with the
gasket, apply it to the gasket before placing the gasket.
3. Apply the antenna element to the top of the mount and tighten it in a clock-wise direction (as viewing
from the top). Use an appropriate wrench if required. Do not
over-tighten.
4. Install a placard (not supplied) on the vehicle’s dash panel, in accordance with the following
CAUTION. Place the placard in plain view of the vehicle operator’s position.
Before entering any automatic vehicle (“car”) wash equipment, remove the antenna
element from the antenna mount, and secure the element in a safe location inside the
vehicle. This will
prevent the wash equipment from damaging the element and/or
mount. After exiting the wash equipment, thoroughly dry the top of the mount before
re-installing the element.
5. Continue with the connection procedure presented in the next section.
6.2.5 Installing the Coax Cable and TNC RF Connector
1. Route the coax cable from the antenna mount to the location where the mobile radio will be installed.
Remove headliner panel, interior panels, etc., as necessary. The cable must be kept out of casual
contact from persons within the vehicle. Tie and stow the cable as necessary to protect it from
possible chafing. Observe and follow this WARNING:
Do not cut an antenna cable any shorter than six (6) feet (1.83 meters), as measured
from the base of the antenna mount to the TNC connector that mates to the radio.
2. Using an appropriate crimp tool, crimp the supplied TNC RF connector to the end of the antenna
cable. For crimping instructions, see Figure 6-6 or the instructions supplied with antenna mount.
3. The antenna cable is connected to the radio’s TNC receptacle-type (female) RF connector per a
procedure presented later in this manual. The cable and its TNC connector must be protected from
damage, dirt, and/or metal shavings which may be generated during the mechanical and electrical
installation of the radio. Temporarily tying the connector and cable-end within a small plastic bag is
recommended.
