1. Select an area on the roof for the base mount keeping in mind the following IMPORTANT POINTS:
a) The antenna should be mounted with the coax channel towards the rear of the vehicle.
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” 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. Carefully pull out the adjustable connector (or the extension if installed - see page 2) 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.
4. Connect the coax from the power injector’s antenna input to the open connection on the splitter in the base mount.
(The coax may come up thru the roof or enter thru the coax channel.)
5. Apply sealant to ring seal and base mount, and ll the coax channel with sealant. Place the base mount in position with the
adjustable connector and interior coax going thru the roof hole and into the interior of the vehicle. Make sure adjustable
connector (or extension) is centered in hole and the coax channel faces towards the rear of the vehicle.
6. Hold the base mount in position and rotate the antenna by hand. It must rotate freely in both directions until it hits the
stop, without interference from sealant, coax, roof insulation, etc. Fasten the base mount to the roof. Make sure the base
mount is sealed all the way around. Make sure the coax channel and fastener heads are sealed as well.
IMPORTANT! In Step 5, DO NOT get sealant on the adjustable connector (or the extension if installed - see page 2).
IMPORTANT! The installer is responsible for determining and supplying the most appropriate fasteners to secure the
base mount to the roof and weatherproong all holes with roof-compatible sealant.
EXTERIOR BASE MOUNT INSTALLATION
IMPORTANT!
Do not get sealant on adjustable
connector (or extension).
Sealant must be compatible
with roof material.
IMPORTANT!
Coax channel must face
towards rear of vehicle.
IMPORTANT!
Hold base mount in place and rotate antenna in one direction until it hits
stop. Rotate antenna in opposite direction until it hits stop (slightly more
than 360°). There must be no interference thru full range of motion.
