The choice to use broadcast television is becoming more common. The cost of cable is frequently seen as one place to tighten the budget. Even a high end HDTV antenna is likely less than one month of cable fees. Getting a good antenna can seem like rolling the dice, but that is not the case. The answers to some questions can make your choice much simpler. It all starts with those answers.
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 are various ways to discover what stations are out there in your neck of the woods or city. The retailers can input your address and give you a list of what broadcast channels you could receive. They often can give you a good idea of how easily any one station might be captured.
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.
However, if one or more of the signals you want to acquire is quite weak, you may want to consider a roof installation. There are at least two types to consider. Directional arrays must point toward the signal. If everyone is broadcasting from the same tower you get them all. But if you want one that comes from another direction you will need to either turn the antenna by hand or get a motorized tuner that will move it mechanically from inside. These may breakdown of course. So, there is yet another option.
The omni-directional roof installed antenna is a round disk. It accepts signals from all directions. It generally has a small powered amplifier that allows weak signals to be boosted to reasonable quality. It can cost around one hundred dollars. It is still less than a single month of cable but among the most expensive.
So there are several varieties of the HDTV antenna out there. Costs range from less than twenty five dollars to over one hundred dollars. Which one you might want will depend on the reception strength of the stations you want as well as the amount you want to invest. But knowing which stations are out there is where to start.
