PF-7

Congratulations! your Terrestrial Digital antenna will provide the
best possible HD picture quality (Yes, even better than cable or
satellite). Here are a few simple tips to make the installation
as simple as possible and optimize the performance of your new
antenna.

Your new antenna will provide the local/over the air (OTA) Digital
TV stations. This antenna will not provide cable channels. There are currently 3 ways to decode your local DTV sta­tions utilizing the antenna:

1. An HDTV with a built in digital tuner. Most TVs sold after 2007 will have these built in.

2. An over the air digital tuner. If the owner’s manual does not specifically state a digital tuner is included, you
will need a set top box (ATSC tuner).

3. An HD satellite tuner. Dish Network and DirecTV offer HD receivers with over the air digital tuners built.

Please note that that once the antenna is mounted and plugged into the appropriate source on your Digital
TV (DTV) or Digital Tuner, you will need to perform a channel scan. If the antenna is moved, the channel scan
must be performed again.

Installation Tips

1. Once the antenna is mounted and the cable is connected , run the cable to your digital tuner, HD satellite
receiver or digital TV (The shorter the better)

2. Perform the channel scan. (Please consult your TV manual for instructions.)

Note: With digital television, it’s an “all or nothing” proposition. On a digital channel you will never see “snow” or
“fuzz” If you see “snow” then you are tuned to an analogue broadcast. Once a digital signal is acquired, it will be per­fect. If that signal is interrupted, it will be blank.
In areas with buildings or reflective surfaces,
multi-path interference (reflected signals) can
cause drop outs in the image.

Trouble Shooting Tips

Short, simple cable runs are best

If your signal is weak, check the length of your cable run and remove any splitters or diplexers. I you use a splitter, you
may want to consider a pre-amplifier.

Higher is better

DTV signals are line of sight. Be sure to clear any obstacles in between you and the transmitting towers. Often, experi­mentation with antenna location resolves a problem. Keep the antenna away from any metallic objects.

DTV tuners can fail

There may be issues with your digital tuner. Faulty decoding chips or bad firmware can affect sensitivity making it dif­ficult to tune digital stations.

Reflected signals (Multi-path interference) are often a source of problems

For those living close to transmitting towers, multi-path interference occurs when strong signals bounce off nearby
buildings and other surfaces causing signal dropouts. An attenuator can allow users to dial down the signal to reduce
problems associated with this multi-path interference.

Common causes of signal loss: (approximate)

• Long cable runs - 30% loss for every 100ft of RG6

• Satellite Diplexers -10%-50% loss

• Splitters - 50% loss per port

• Corroded connections - 20% -90% loss
