If you watch fuzzy TV long enough, you might start getting used to it, that is until you see a crystal clear picture elsewhere and then go back to your fuzzy screen. If you have this problem, or if you want to be able to receive local channels when not watching your cable or satellite programming, you need to look into a TV antenna. The only problem is deciding which one to buy.
Should you get an indoor TV antenna, or an outdoor one? Do you want something inexpensive and simple? Do you need more than one?
First, learn what types of signals you need to receive. If you don't need to receive UHF channels, or those above channel 13, don't buy a UHF/VHF antenna. Stick to the VHF type, which will also provide reception for FM radio. If you need all three, you can get a combination TV antenna, designated UHF/VHF/FM.
A lot depends on how many stations you hope to receive and in which direction they are located. If you want to receive signals from several stations in different directions, you may need a "rotator." You can adjust the rotator as needed to pick up a specific signal. This may of course lead to problems if you have more than one television in the home, and they are being watched on different channels simultaneously. If you rotate the TV antenna toward the station you want to watch, others in the home may lose their signal or receive a weaker signal.
If your family has more than one television, you may want to opt for an indoor TV antenna for each one. You can position the antennas to point in the direction of the station each person wants to watch. It helps if the TV is positioned in a way that allows the TV antenna to point towards a window or an interior wall. Exterior walls, heavy doors, and high ceilings may decrease reception.
When you are shopping for a TV antenna, you will likely notice a mileage rating on the package. This rating should not be the deciding factor, since other factors play a role in reception. Things like trees and other homes can block the signal, so make your selection based on other criteria, rather than just the mileage rating.
