To determine antenna installation
location, there are several factors
to be taken into account. First
thing is antenna propagation
direction to specific target
stations. As to whether there are
any obstacles such as tall build-
ings on the line of sight. Next is
specific installation location. As to
whether specific location is
adequate in terms of antenna
support and surrounding safety.
• Do not attempt to install the
antenna by yourself if you do not
have any experience in installing
base station antenna. Ask
your experienced friends or a
professional for help.
• Do not attempt to install the
antenna at a location where it
does not have enough distance
from nearby electric power lines.
It is advised to install the antenna
at least twice of total antenna
height from nearby electric
power lines.
• Do not install the antenna on any
type of tower, pole or
telescopic mast which exceeds
30 feet high, if you do not have
enough experience in installing
the antenna on that kind of
location. Ask your experienced
