Power lines
Power lines are usually not a problem. As long as the RAU is at least
10 feet away from the power lines, the signal will be able to go
through the power lines without a problem. Power poles can block
the signal however. Try to avoid having power pole blockage. If it is
impossible to avoid power pole blockage, try to locate the Globalstar
RAU as far from the power poles as possible.
Television antennas
Many homes have tall television antennas on their roofs. It would
often be quite difficult to put the RAU high enough to avoid having
the television antenna in the way. Good news! You do not have to
put the RAU higher than the television antenna. If you locate the
RAU at least 10 feet away from the television antenna and mast, the
television antenna and mast will not cause blockage. (This presumes
a standard 1 1/2 inch diameter television antenna mast. If, instead
of a simple mast, you have a large antenna tower, then you should try
to locate the Globalstar antenna farther away.)
Trees
Trees are almost always bad for satellite reception. Try to avoid
them. The Globalstar signal will go through some thin trees.
However, trees will grow, and the problem will get worse over time.
Trees also cause much more blockage when they are wet. The signal
may find its way through the trees this afternoon, but have more
trouble in the evening after the sun sets and dew forms on the leaves.
Try to avoid having trees in the way of your satellite signals.
If a house is surrounded by trees, you should consider putting the
Globalstar RAU on a mast, extended up from the roof of the house.
Ideally, the mast would be tall enough so that the antenna of the
RAU can see most of the sky.
Chimneys
The Globalstar signal will not go through a chimney. If you mount
the antenna on the side of a chimney, the signal will not be able to go
through the chimney, so the antenna would only see half the sky.
That's bad.
10
If you attach a mast to a chimney mount, then extend the antenna of
the RAU above the chimney, you may have a good installation.
However, soot from the chimney may accumulate on the antenna
over time. Soot contains carbon that will block the signal! Soot
buildup will cause problems. If your fireplace burns anything but
gas, avoid putting your RAU in that location. If the chimney is fed
