Roof Mounting Instructions
Preparing the Hole
1.
After selecting the location to mount the Antenna,
mask the mounting location to avoid paint damage.
Mark the hole center with ink or scribed cross hairs.
2.
Use a center punch to make a dimple on the marked
location to avoid drill bits from walking across the
sheet metal. Use a Twist drill of diameter about 0.1”
and drill a pilot hole. Using a 1.0” diameter sheet
metal hole saw, drill the hole.
3.
The hole saw will cut the required diameter hole with
less risk of stretching and distorting the vehicle
surface.
4.
Clean up any metal shavings around the mounting
location.
Mounting the Antenna
1.
Feed the coaxial cables from the antenna through
the hole from the outside surface to the inside
surface and thread the entire length of the cable
through the hole.
2.
Clean debris off the vehicle surface and then
mark the desired antenna orientation by placing
the antenna flat on the vehicle surface.
3.
Lift the antenna and remove the protective
backing from the underside of the antenna and place the antenna back in the desired position.
Apply downward pressure on the antenna to stick it to the panel. This step is optional if you plan to
mount the antenna magnetically.
4.
To avoid the gap between the antenna and panel, it is
recommended to use neutral cure silicon sealant around the
base of the mounting boot to fully compress the antenna to
the mounting panel.
5.
A split flat washer and a split hex nut are provided in the kit
for easy installation.
6.
On the inside of the vehicle, thread the flat washer over
the cable, followed by the PTA0257 star washer (if
applicable) and then hex nut.
7.
Slide the washers and nut to the threaded flange of the
antenna and tighten the hex nut until antenna
compresses flat with the surface of the vehicle.
