Common Radio Reception Conditions Several conditions prevent FM reception from being completely clear and noise-free, such as the following: 1. Distance/Strength The strength of the FM signal is directly related to the distance the signal must travel. The listenable range of an average FM signal is approximately 25 miles (40 kilometers). Beyond this distance, the radio is operating in a fringe area and the signal becomes weaker. NOTE: Always make sure your antenna (whether you have a power antenna or a manually adjustable antenna) is fully extended to its maximum length for proper reception. If your antenna is not fully extended, you may experience signal loss while traveling in fringe reception areas. 53
