TV Antenna FAQs, answered by experts

Before investing in a TV antenna repair, there are a few steps you can take to help boost your signal quality. Removing obstacles like tree branches can help improve your signal strength. Along the same line, moving an indoor antenna away from obstacles can also help. These should be near a window, as high as possible. If these steps don’t work, speak with a TV antenna technician about a signal amplifier to help boost your signal even further. 

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.

The easiest way to ensure you get the best reception from your TV antenna is to leave the installation to a professional. You’ll pay around $300 for this service, but the expert will use signal checkers to find the ideal placement for your antenna on your roof. They can also determine the right direction for your antenna to face. If your existing antennas are delivering a poor-quality picture, it might help to invest in a TV antenna signal booster, which picks up more signals and could provide a better experience.

Outdoor TV antennas are often worth it, as the signals broadcast in your area are always stronger outside. If you have an indoor antenna that isn’t performing well, call a TV antenna installation company to come out and use a signal checker to see if a stronger signal is available on your roof, as it often will be. Outdoor antennas require longer cables, which can decrease the quality of the picture, but a professional should be able to find a position where cable length is minimized, and the available signal is strongest for ideal performance.

Annual checks for damage or misalignment and ensuring clean connections.
