I guess you don't get much snow on the ground in Az.
Can't mount dishes close to the ground here or they'd be stuck in the snow in the winter. Last 2 years I had to trudge out through 3 to 4' deep snow, and dig out my Fortec dish. Not to hard to get it free of snow to see the sats, but the problem was that it couldn't move until I dug all around it. I learned this year not to let my coaxes dangle around on the ground off the lnbf, because they got stuck in a layer of ice, and I couldn't move the dish until I got the coax out of the ice.
I guess in Az, all you have to worry about is a sand storm.
No snow in the desert. Or at least not enough to accumulate on the ground.
