rmmrph said:this is one that you should check with your neighbors. It is highly dependent on your location (hills/mountains or large obstructions) and the distance to the broadcast towers. If you are in an urban area. I would recommend the silver sensor type antenna, to limit multipath. If you not sure exactly where the broadcast towers are located you can find out using antennaweb.org. I am located about 25 miles from the towers in Philadelphia, and I using and outdoor UHF antenna mounted in my attic.
