You may be considering a change to broadcast television from cable TV. The cost is certainly less than cable. Even buying an antenna costs less than most cable fees and is a one-time expense, not monthly. But choosing the right HDTV antenna will require some homework. Once some questions have been answered, you should have a better idea of which ones might be right for you.

You will need to know what channels are available over the air. These broadcasts channels are accessible by line of sight. That can be a problem if you live in a city with tall buildings on every side. But you can find out just what is out there by doing a little web surfing.

There is a nonprofit website where you can input your address and receive a list of stations and their relative signal strength. The list is color coded and will give you the strength and even the direction those signals come from. If one you really want is weak, you can choose the sort of antenna that will pull it in. It is likely your retail dealer can give you this information as well.

The sorts of antennas available are table top or TV top antennas as well as several sorts of roof top antennas. If your location is flat and unimpeded, then set top might work. Your investment could be smaller than the roof top arrays.

Some options are more expensive. A rooftop array generally needs to be positioned to best receive a broadcast signal. If many of the stations are broadcasting from the same tower, arrays work well. But, if signals come from several directions and at different strengths, then tuning will be difficult. There are motors that allow you to change direction from inside but they can cost a lot.

Another alternative to directional arrays is the omni-directional antenna. These are circular disks up to several inches thick and installed on the roof. They also have powered amplifiers that can boost weaker signals. They can receive signals from all directions and require no tuning.

So, while there are table top sets, directional roof arrays and omni-directional roof antennas, just which HDTV antenna you will choose will depend on a number of things. The number of available signals, the strength of those signals and the investment level you are willing to make for the quality of reception.
