When we put our Directv dish in, we located it on a low flat roof near a=20
2nd story bedroom window. When it gets snow covered cutting reception, I=20
just stick a broom out the window and dust it off. Ice hasn't been a=20
problem in 8 years, but there is a first time for everything. I have=20
seen electric resistance heaters that go on the back of the dishes,=20
don't know how good they work. I suppose if need be, I could duct tape a=20
heat gun to the broom and melt ice that way. Or just take the garden=20
hose preferably with hot water, and blast it away.   :)
