I just wanted to post my experience with the "Coat Hanger Antenna" that has been seen on the internet. http://www.metacafe.com/watch/762088/coat_hanger_hdtv_antenna_better_than_store_bought_amazing/ The process involves creating an 8 element UHF antenna out of a board and coat hangers (as the name implies). All I can say is, IT WORKS!!! I built mine using copper wire (12 ga). Other than that, the only modification I added to it was 2 6 foot wires added at the matching transformer so it will pick up the VHF in addition to the UHF. Best of all, it didn't cost me a dime since I had all the supplies already. I have it mounted in the attic of a one story house and my signal strength is in the low 70's to 100 YMMV. Now if only I could get DTV to add all the sub channels to my AM21.
