DTV Tuner Signal Strength Indicator
If your DTV set top box or DTV tuner in your TV has a signal strength indica-
tor (refer to that components 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.
3. 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 tow-
ers 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, secure-
ly 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
(fig. 7) (sold separately).
Analog TV Pointing Method
This method uses a conventional analog TV to chose the best spot for a DTV
antenna.
1. Place antenna in as 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
30 feet above the ground pointed directly in the “line of sight” of the broad-
cast antenna (Line of sight means that there are not any obstructions between
the broadcast and receiving antenna such as buildings, water towers, moun-
tains 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
