How do I Make an Antenna Receive a Stronger TV Signal?

By Jennifer Underwood

Consumers with a television antenna may receive free local-channel high-definition programming. It is challenging to find the right antenna and get it to receive the channels you want. There are a few basic rules for better reception.

Step 1

Put your antenna outside. Antennas get the best reception when in the open air without obstruction. Putting a television antenna in the attic will cause interference and take up valuable storage space.

Step 2

Choose a large antenna. Very High Frequency (VHF) channels (1 through 13) use large wavelengths, so they need large signal elements. With these channels, the strength of the signal is directly related to the length of the receptors.

Step 3

Raise your antenna higher than your roof line. It is best to have your antenna positioned above any source of interference such as your home or surrounding buildings and trees. Signals will not only bounce off of your roof, but the antenna may also pick up signals from other electronics in your home causing weaker television signal reception.

Step 4

Position your antenna in the direction of the broadcasting tower with as few interferences as possible. If you cannot position your antenna above your roof line, place it on the side of your home closest to the broadcasting station. Be conservative when running the coaxial cable from your antenna to your home. Signal strength can be lost while traveling through a long cable.

Step 5

Add a preamplifier to the antenna. The signal booster will help bring in weaker channels. A preamplifier may also help if your television tends to loose signals under cloud cover.
