For Your Safety
Please read the following safety precautions
before antenna assembly.
• Assemble the antenna on the ground or wide and
flat place such as on balcony before installation.
• Do not assemble or install the antenna on a place
where you can not have enough distance from
any electric power lines.
• Do not install the antenna on a rainy or windy day.
• Do not attempt to install the antenna only by yourself.
Installing the antenna alone on the roof may lead you to a
dangerous accident. Always ask your friends or a profes-
sional for help installing the antenna.
• Do not use iron or aluminum ladder at a reachable
distance from any electric power lines.
• Do not install the antenna on a mast which is not
grounded properly.
• Do not have your family members or friends touch or
come close to the antenna, unless they have realized its
potential danger.
TO AVOID FATAL ACCIDENT
• Do not attempt to sustain the antenna, or any part of
support structure if it begins to fall down. Let it fall by itself.
• Do not attempt to remove or restore the antenna or any
part of support structure if it touches an electric power
line. Let it be as it is, do not touch it, and call your local
electric power company immediately.
IN CASE OF AN ACCIDENT
• Do not touch a person or an animal who is or seems to be
in contact with the antenna or any support structure which
is fallen on a live electric power line. Touching one may
lead you to be electrocuted.
• Do not attempt to separate a person or an animal who is
or seems to be in contact with the antenna or any support
structure which is fallen on a live electric power line by
yourself. Call or have someone call a police officer,
ambulance, or doctor immediately.
Antenna Installation Precautions
To determine antenna installation location, there are
several factors to be taken into account. First thing is anten-
na propagation direction to specific target stations. As to
whether there are any obstacles such as tall
buildings 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 anten-
na. 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 friends or a pro-
fessional for help.
• Do not use more than 1/10’ section if you install the
antenna on iron plumber’s pipe. Attach guy wire if multi-
ple pipes are used to install the antenna.
