External Installation (where optional external aerials have been supplied)
Safety
Installation of this antenna near power lines is dangerous. For your safety, follow these instructions.
Select your installation site with safety, as well as performance in mind. Remember: electric power lines and
phone lines look alike. For your safety, assume that any overhead line can kill you.
When installing your antenna, remember:
•
Do not use a metal ladder.
•
Do not work on a wet or windy day.
•
Do dress properly
—shoes with rubber soles and heels, rubber gloves, long sleeved shirt or jacket.
If any part of the antenna system should come in contact with a power line,
don’t touch it or try to remove it
yourself. Call your local power company. They will remove it safely. If an accident should occur with the
power lines call for qualified emergency help immediately.
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 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.
The antenna is designed to create an omni-directional broadcast pattern. To achieve this pattern, the
antenna should be mounted clear of any obstructions to the sides of the radiating element. If the mounting
location is on the side of a building or tower, the antenna pattern will be degraded on the building or tower
side.
Before attempting to install your antenna, think where you can best place the antenna for safety and
performance. Install your antenna at about 8 to 10 feet above the ground and away from all power lines and
obstructions.
Mounting the Antennas
The antennas should be mounted externally and as high as possible but ensure they are clear of any power
lines. The antennas should be spaced about 1 metre apart. The antenna is vertically polarized. Since the
antenna has vertical gain, it is very important to mount the antenna in a vertical (not leaning) position for
optimal performance.
