Signal loss, loose mounts, cable damage, and weather-related wear often require repair.

Yes, in general, raising your TV antenna will improve your reception. Besides raising the location of your antenna, you should try putting it by a window. In fact, you can have the same antenna but get double the channels or more if it's in the best location. The highest spot to put a TV antenna will be on your roof, and the tallest type of outdoor antenna is a tower.

If you’re having problems with poor reception, here are some simple tips that may help improve the signal and picture quality.

• Consider the position of the antenna: Could it be higher, is it secure, or are nearby obstructions interfering with the signal? For a directional antenna, you may need to reposition it in the direction of the broadcast tower.

• Move any metallic objects: Metal can interfere or block reception, so if you have stainless steel objects or the antenna is near a wrought-iron fence, this could be a problem. Try to keep the antenna at least six feet away from metal objects..

• Cable length: An overly long cable can reduce signal strength. If you don’t need as much cable as you are using, it may be better to exchange it for a shorter one.

There aren’t any guarantees that the TV antenna you purchase and install will provide perfect reception. Much depends on your distance from broadcasting towers, any nearby obstructions, and typical weather. However, doing some research minimizes the risk of disappointment.

You can speak to neighbors to understand their setup. Various online tools allow you to check how far you are from TV transmitters in your area. The Federal Communications Commission, for example, has a tool enabling you to check local Digital TV channel reception.

Selecting the right type of antenna for your situation and having it properly positioned and installed will also increase the chances of better reception.
