For Your Safety

Please

read

the

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 dis-

tance 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

professional 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

following

safety

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

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

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 friends or a

professional for help.

• Do not use more than 1/10' section if you install the

antenna on iron plumber's pipe. Attach guy wire if mul-

tiple pipes are used to install the antenna.
