battery without taking steps to continue to supply electrical power to these components could adversely
affect the operation of the vehicle.
Routing the power and antenna cables through the vehicle is very important. Hazards such as sharp edges,
chafing surfaces and pinching can cause electrical shorts in the wiring causing it to fail or interfere with
proper function. Possibly damaging the unit or vehicle. Be aware of what could cause these problems and
take appropriate preventative steps.
Warning!
Installing the power connections improperly can result in damage to the device and/or the vehicle. It is
advised only trained technicians install this device.

1. Cradle installation:
Installation Notes (2):
Caution
–
Keep in mind the VC1727C cradle weight is approximately 5 lbs. and the mounting surface
should be able to support 3 or more times this weight. Wiring or other electrical components could be
concealed behind mounting surfaces and care should be taken not to damage them when installing the
cradle.
-----------------------
Step 1:
Select the mounting location for the VC1727C cradle. Remove the ball from the unattached end of
the Round-A-Mount armature. Set the cradle aside and using the unattached ball mark locations for the
screw holes on the attachment surface.
Step 2:
Drill holes through the mounting surface using a 5/32-drill bit. Then with 8-32 machine screws and
self locking nuts or nuts with lock washers attach the Round-A-Mount ball to the mounting surface.
Step 3:
Connect the cradle to the mounted ball utilizing the Round-A-Mount armature and adjust to the
preferred position.

Attaching antenna cable terminals:
Installation Notes (3):
When attaching the antennae terminals it is critical the connections are solid. Nicked, broken and poorly
connected coax cables can cause RF signal leakage. This will severely reduce the efficiency of the
antennae and could cause antenna failure.
In the past installers have asked us not to terminate the antennae cables because of the difficulty running
the antenna cable inside the vehicle with the terminal installed. They found it easier to install the terminal
after they ran the cable. For this reason the antennae we shipped to you didn't have the TNC and BNC
terminals attached.
If desired future antennae shipments can be shipped with the antennae terminated by request when placing
your order.
-----------------------
Step 1:
To install the terminals the following tools are needed:
1. Coax wire stripper(s) for RG-58 and RG-174 cable
2. Coax cable crimp tool with a RG-174 die.
3. Coax cable crimp tool with a RG-58 die.
