To install a rear-mounted antenna:
1. Determine the antenna base mount and support bracket attachment points. You will
NOT be able to re-align the base plate mount or upper support bracket once
they are in place.
Make sure there is a minimum of 48" between the antenna base
mount and the upper support bracket. Draw a vertical centerline on the truck
extending from the base plate location through the upper support bracket location.
The brackets will be mounted along this centerline at the intersection of a cab support
framing rivet line, with the antenna base mount as close as possible to, but no more
than, 75" above the ground.
Note: The antenna performance improves as its height above the
ground increases.
WARNING! FEDERAL MOTOR CARRIER SAFETY
REGULATIONS PROHIBIT THE OVERALL HEIGHT FROM
EXCEEDING 13' 6". BE SURE THAT THE OVERALL ANTENNA
HEIGHT IS LESS THAN 13' 6".
CAUTION! Rear Base Mount and antenna support must be attached where
rear cab skin is supported. Attach them to locations where there is framing
behind the cab skin. This is the intersection of the centerline and a rivet
line.
WARNING! CHECK BOTH SIDES BEFORE DRILLING. DRILLING
INTO A WIRE CAN CAUSE A FIRE. DRILLING INTO AN AIR LINE
CAN CAUSE BRAKE FAILURE.
