WARNING
If a person comes in contact with electrical power, and cannot move:
DON’T TOUCH THAT PERSON, OR YOU MAY BE ELECTROCUTED.
Use a non-conductive dry board, stick or rope to push or drag them so they no longer are in
contact with electrical power.
Once they are no longer contacting electrical power, administer CPR if you are certified, and
make sure that emergency medical aid has been requested.
Choosing a Mounting Location
The location of the antenna is important. Objects such as metal columns, walls, etc. will reduce
efficiency. Best performance is achieved when antennas for both Multinodes and SmartLine
Transmitters (Leaf Nodes) are mounted at the same height and in a direct line of sight with no
obstructions. If this is not possible and reception is poor, you should try different mounting
positions to optimize reception.
Antennas should be mounted clear of any obstructions to the sides of the radiating element. If the
mounting location for an omnidirectional antenna is on the side of a building or tower, then the
antenna pattern will be degraded on the building or tower side.
Site Selection
Before attempting to install your antenna, think 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
Action
1
Measure the height of your antenna.
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 your antenna is above the ground, the better it performs. Good practice is to
install your antenna about 5 to 10 feet (1.5 to 3 meters) 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 direct as possible.
