7 Digital TV Pointing Method

This method uses a conventional analog TV to choose the best spot for a DTV antenna.

1Place 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 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.

2Tune your analog TV to a UHF TV channel (channel 14 or higher) that is on the same broadcast tower or tower location as the DTV stations you are trying to receive.

If you do not know this information you can call your local TV station’s engineering department and ask them. If you have internet access, Antennaweb.org is also helpful. (www.antennaweb.org)

3Slowly rotate antenna or walk location area with antenna while monitoring your analog TV. Find the location that has a stable picture with the least amount of ghosting.

4Very often, ghosting can be minimized if you rotate your antenna until the picture improves. Unfortunately, sometimes there is no solution for the problem due to surrounding terrain/obstructions. You are looking for a picture that is clear and free of ghosting.
