EXTERIOR BASE MOUNT INSTALLATION (FIG. 2)
1. Select an area on the roof for the base mount keeping in mind the following
IMPORTANT POINTS
:
a) The point of the base mount with the adjustable connector should face the front of the vehicle (Fig. 1).
b) The center of the roof hole must be at least 20” away from any object taller than 8” to provide clearance for the
antenna head to rotate freely. The center of the roof hole must also be at least 8” from the edge of the roof.
c) For roof thicknesses 1 1/4” to 6”, the roof pitch can not be more than 3 degrees.
d) There must be room on the interior ceiling of the vehicle to attach the rotation knob and enclosure to the
adjustable connector. The interior enclosure can be mounted in any direction.
2. Drill a 2 1/4” hole
perpendicular to the roof surface
all the way thru the vehicle roof where the adjustable connector will go.
3. Inside the vehicle, place the enclosure base over the hole and against the ceiling in the position it will be mounted. Mark the
coax hole on the ceiling. Enlarge the
interior roof hole only
at this location to accommodate the coax cable where it will exit the
roof and enter the enclosure base
(Fig. 3)
.
4. On the roof of the vehicle, carefully pull out the adjustable connector so it will extend beyond the thickness of the roof when the
base mount is installed. It must extend thru the roof to allow installation of interior components. Exact length will be adjusted
when interior components are installed.
5. Connect the coax from the antenna input of the Power Injector to the open connection on the splitter in the base mount.
6. Apply sealant to ring seal and base mount, and fill the coax channel with sealant. (Butyl tape may be used in combination with
sealant.) Carefully place the base mount in position with the adjustable connector and coax going thru the roof hole and into the
interior of the vehicle.
Make sure the point of the base mount with the adjustable connector is pointed towards the front
of the vehicle.
7. Center the adjustable connector in roof hole and fasten the base mount to the roof. Use the mounting holes in the base mount as
a guide to install the fasteners (determined by the installer) into the roof. Make sure the base mount is sealed all the way around
and the coax channel is fully sealed as well.
ALL EXISTING HOLES MUST BE SEALED!
IMPORTANT! The installer is responsible for determining the most appropriate fasteners to secure the base mount to the
roof and weatherproofing all holes with sealant. The installer is responsible for sealing all existing holes
when replacing an existing antenna mount.
IMPORTANT! In Step 6, ring seal sealant must not get on the adjustable connector.
