Yep. If its low to the ground, just a broom will do, If its caked on Ice, Just Use Hot water from the faucet.
It will Not refreeze worse!!!!
If its High up, the supersoaker with Hot water works great!
Snow shouldn't be an issue unless the Temp is over 28 degrees or freezing rain is mixed in.
Snow fall in the low 20 degree range or less should not effect your signal since the colder it is the lighter the snow and contains less water. (Less Dense).
Living in the Pocono Mt's you learn a thing or two about snow.
Snowfall with temps over 30 degrees or freezing rain are you signals worst nightmare.
Moderate or Heavy Sleet will also cause signal Fade, but won't stick to the dish.
Good luck. 5-8 inches is nothing to worry about.
