Snow stuck/frozen onto sat. dish.

Did say you are trying to keep snow off it or cook on it.

???? 200 watts will not cook anything. And less than 2 amps current draw.

I would try rain-ex. I bet that would work in the cold just fine.

I see what you are saying but sorry the comparison between your oven sitting in a home at room temperature and a roof mounted dish exposed to the elements simply are not part of the original thread question. My response was in reference to the subject matter which is a satellite dish.

The metal is thin and the spot you put the block heater will be pretty hot. Not going to turn it into a wok, but it may get warm enough to damage the paint under the heater.

Good points! Was hoping that if attached at the bottom of the dish the heat would radiate up through the metal and simply melt the snow bottom to top. The surface area of the dish would also dissipate a lot of the heat but your right about the one hot spot. The block heater being on the back side it would not really matter if it blistered a bit. Could always spray the area with high temp bbq paint if it was a problem.

The other idea I had was to epoxy pipe heater cable on the backside of the dish in a circular fashion.
Again, I never got around to this project as I cut the cord and have an indoor HDTV antenna. No more climbing the ladder to clean the dish.

Commercially, these are available.

The Never Wet sprays work great but it's too cold to use it now.
