Slowly rotate antenna on mounting mast
in both directions until the highest signal
strength is achieved on the DTV tuner.
Check all DTV channels to make sure the
signal is good on all channels you desire to
receive from the DTV broadcast tower that
you are pointing at. If you have two DTV
broadcast towers in two distinct directions
and are not able to receive all DTV stations
broadcasting in your area install the antenna
with a rotor.
4
Watch DTV channel for a few minutes to
make sure picture is consistently stable
without freezing, disappearing or breaking
up. If picture is stable, securely mount
antenna per enclosed mounting instructions.
5
For best results, do not run signal through
diplexers or splitters, run new RG6 coaxial
cable from antenna location directly to your
DTV receiver. If you have a cable run of
more than 100 feet or need to run through
diplexers and/or splitters use a signal
preamplifier that is installed as close to the
antenna as possible.
6
To avoid signal loss, do not attach the
coaxial cable to the mast, use standoffs.

Tip
Do not use a convention signal strength meter
for installing a DTV antenna. Chances are this
will give you false information and cause the
antenna not to work reliably. Severe ghosting
is the number one reason for DTV reception
problems. Most severe ghosting occurs in
locations where there is plenty of signal
strength. A conventional signal strength meter
will find this location.
6 DTV Tuner Signal Strength
Indicator
If your DTV set top box or DTV tuner in your
TV has a signal strength indicator (refer to that
component's user manual) you can utilize this
feature for selecting a location for installation
and aiming the antenna.
1
Locate antenna in a high location with as few
obstructions in front of, behind, or to the
sides of the antenna as possible. Optimally
the antenna needs to be at least 30 feet
above the ground pointed directly in the
“line of sight” of the broadcast antenna
(Line of sight means that there are not any
obstructions between the broadcast and
receiving antenna such as buildings, water
towers, mountains or trees. Line of sight
does not mean you need to be able to see
the broadcast antenna with your eye). If
you are able to achieve this “line of site
installation and do not have severe multi-
path problems such as in a very dense high
rise area, you will in most cases receive a
good stable DTV and Analog TV picture.
2
Connect the antenna to your DTV tuner
with a good quality transmission line.
