Although there are many causes for a TV to not receive a signal, this is usually caused by the antenna not having a clear line of sight to the broadcast towers. Anything blocking the antennas line of sight will disrupt transmission. This includes buildings, hills and other geographic features, etc. Elevating the antenna higher will often provide the solution to this problem. The goal is to get the clearest view to the broadcast tower as possible. If you’re having trouble, give us a call.
