Installing the Antenna
Site Selection
Before attempting to install your antenna, determine where you can best place the antenna for safety and
performance.
Follow these steps to determine a safe distance from wires, power lines, and trees.
Step 1
Measure the height of your antenna.
Step 2
Add this length to the length of your tower or mast and then double this total for the minimum
recommended safe distance.
Caution
If you are unable to maintain this safe distance, stop and get professional help.
Generally, the higher an antenna is above the ground, the better it performs. Good practice is to install
your antenna about 5 to 10 ft (1.5 to 3 m) above the roof line and away from all power lines and
obstructions. If possible, find a mounting place directly above your wireless device so that the lead-in
cable can be as short as possible.
Installing the Antenna
You can install the antenna on any flat vertical surface. Hardware for mounting the antenna on drywall
is provided. If you intend to install your antenna on another surface, you must provide the appropriate
hardware.
Note
Four mounting screws are provided to mount the antenna . To ensure a safe, reliable, and long-standing
installation, you must use all four screws to mount the antenna.
