RoyB; When the cable company dropped all analog signals, thus requiring a cable box for each TB in the house, I realized that we could receive all the local channels with our Sensar IV and Sensar Pro in the RV parked outside out house. So I got one of the Flat sheet antennas with an amplifier and stuck it up in one our our windows. Works almost as well as the RV antenna. Thought about one of the outside mounted UHF ones, but the cheaper solution works well enough for our use. BTW, know where Clydedale is?? Thats where one of our kids reside. But we can't get the RV in her driveway.
