There are many varieties of signal amplifiers available today. These also come
in VHF only, UHF only or Combination. They also come in various gain levels.
The higher the gain, the better. Keep the following in mind: A Good Amplifier
Can Not Make Up For an Incorrect Antenna.
Put your efforts into the proper
antenna system first, and then add the correct amplifier to improve the frequencies
necessary. Make sure the amplifier is rated for all UHF channels. Always use
a two-part amplifier. One-piece mounts just below the antenna, and the power
portion sits behind the TV. With this style, you are amplifying the best possible
signal. The one-piece amplifiers not only amplify the desired TV signal, but
also any unwanted noise picked up by the wire. This will only give you a more
powerful noisy picture.
