We have 9" of snow blowing around here now, with 25MPH wind and -8. There is snow/ice stuck to the dish, but signal is still good enough to get a picture. We did clear off the LNBs once last night at the height of the storm.
We've got about a foot of snow but I have ZERO on my EA dish on the roof. I've had 3 small Katz heaters (made for engine blocks,etc., available from Amazon) stuck to the backside for 3 years now. When it starts to snow I plug in the extension cord that runs up to the dish, problem solved. Just wish I'd ran a heat cable around the LNB's arm. The snow is right up to the LNBs but no problem yet.

I've had to three times since noon. Over six inches of expected 10-12" in Indianapolis.
Tampa, Rey...try to resist.
I wonder why satellite companies don't just create a dish with a built in heater that works off the power from the receiver off the coax cable. Integrate it and then you could turn it on at the receiver through your settings when you need it. Then the Sat companies could advertise the fact that you don't have to clean your sat dishes off when it snows or there is ice.
When I got home Friday I found out that there had been no signal all day. 5 inches of snow had fallen overnight, and when I looked at the dish there was some snow which by then had frozen. Because it was frozen I couldn't knock it off, so I filled a pot with hot water and tossed it by the cup full from the Master Bathroom window until the snow/ice was gone. I was surprised at how well it worked, and how good my aim was.
