Im in a apartment building behind another, with some large trees in the area I have 2 large windows at which the antenna is directed at, my apartment is approximately 24 miles from the broadcasting towers, I receive 2 HDTV Channel of approximately 25 available. In short unless you have a clear shot toward the tower you want reception from, do not rely on this antenna to do you the favor of finding the signal. I'll add that you cant use a quality cable (ie Monster) because the cable is hardwired into the antenna at approximately 5' length.
