 Perform as much antenna assembly on the ground as
possible.
 Watch out for overhead power lines. Check the
distance to the power lines before you start installing.
WE RECOMMEND YOU STAY A MINIMUM OF TWICE THE
MAXIMUM LENGTH OF THE ANTENNA ASSEMBLY AWAY
FROM ALL POWER LINES.
 Do not use a metal ladder.
 Remember, even the slightest touch of an antenna to a
power line can cause a fatal shock.
 Do NOT try to do the job on a windy day.
 Have a friend as a spotter when you’re on the roof.
They can see things you can’t.
 If you start to drop an antenna, move away from it and
let it fall.
 If any part of the antenna should come into contact
with a power line CALL YOUR LOCAL POWER
COMPANY! DO NOT TRY TO REMOVE IT YOURSELF! They
will remove it safely.
 Mast, lead-in, and metal guy wires are excellent
conductors of electrical current - - keep them away
from power lines too.
 Be sure your family and friends understand the danger
of touching an overhead power line. Tell them never to
try to remove any object in contact with a power line
(TV antenna, mast or anything else).
 Make sure that the antenna mast assembly is properly
grounded.

For best reception, please consider the following
conditions:
 Keep the antenna away from sources of interference,
including air conditioners, microwave ovens, hair
dryers, etc. These are all sources of strong electrical
interference, and can cause poor quality or total loss of
TV signals.
 Place the antenna near a window, preferably on the
side of the house facing the TV station transmitters,
when installing the antenna indoors.
 Install the antenna as high as possible, and preferably
with a clear path between the antenna and the TV
station transmitters. Trees, buildings, mountains, etc.,
can all impact the performance of any antenna.
