Nothing like the old roof antenna when a ice storm hits the area. Both HD and SD Dish satellite antennas are covered with a heavy coat of ice today. No signal from Dish, so, I have to use the 20' roof antenna to get the locals stations. The signal is not as great as I have the roof antenna cabled though my Dish 211K receiver, and I don't know why or how the signal works when cabled thru the 211K. However, with this setup the signal gets restricted somehow. I must search for some type device to attached and heat the Dish antenna...if there is such a thing.
