If your TV antenna is good quality and was installed by a professional, you can expect it to last between 10 and 20 years without needing repair or replacement. This can vary based on your geographic location, weather conditions, and antenna location. 

The cost to repair your TV antenna is around $200 for the average homeowner. However, charges could be as low as $60 or as high as $450. Factors such as multidirectional or unidirectional, indoor or outdoor, and amplified or non-amplified all play an essential role in determining the cost of your repair. For example, outdoor antennas cost more on average to repair than indoor ones, much like amplified antennas cost more to repair than unamplified ones. 

Options include outdoor, indoor, and rooftop antennas. Choose based on signal needs and location.

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.
