Thanks for the input. I guess i should have added that I am roughly 25 - 35 miles from the majority of the transmission towers for the stations I am trying to watch. Terrain is basically flat. The old antenna was fine for both UHF and VHF in the analog era. Since the changeover I have had difficulty with the digital stations in the 20 - 39 range, while 2 - 13 and 51 - 55 seem to be fine. The old antenna is a standard beam type about 6 feet long and the downlead is old style flat twin lead, not coax. Unfortunately, the downlead runs through the walls down to the living room where my multiswitch is (originally a C-Band setup) and I would have to run new coax on the outside of the house to replace it.
