IMPORTANT POINTS
You will need a drill and drill bit, roof-compatible sealant and appropriate
fasteners to install all components and wiring.
The installer is responsible for determining the most appropriate
fasteners to secure the antenna bracket to the roof. Depending on
the roof material, fasteners such as lag screws, well nuts, sheet metal
screws, toggle bolts and T anchors may be used, and should always be
used in combination with a roof-compatible sealant.
The installer is responsible for properly securing the coax cable to the
roof (for example, cable ties and cable tie mounting pads).
heads with roof-compatible sealant.
Do not put sharp bends in coax cables.
This can reduce signal strength from the antenna.
overlap, a condition called oscillation occurs. Oscillation can be thought of as
noise, which causes the booster to shut down to prevent damage. The best
way to keep these spheres of signal from overlapping is to maximize separation
between the booster and the antenna.
IMPORTANT! The aluminum casing of your signal booster will adjust to the
temperature of its environment, but is designed to protect the signal booster
technology. For example, in the summer, the signal booster case may be
as hot as 150 degrees inside your vehicle. These high temperatures will not
be sure to place your signal booster in a location with adequate ventilation
and away from direct sunlight or moisture.
The signal booster may remain on in vehicles whose 12V DC power sources
do not automatically shut down when the vehicle is turned off. This could
result in discharging the vehicle’s battery in one to two days.

COMPONENT LOCATIONS
components in their chosen locations, completing the setup
instructions, and verifying the system works as desired.
TIP
(Route the cable through an open door or window for the
soft install.)
NOTE: It is up to the installer to determine the best component locations.
