I have a California Amplfier brand dish. We have some cold weather here and my dish starts to break up. I put it up last year and it was not as cold. We have had some cold weather here 10 below and with wind chill makes it about 30 to 35 below zero. I removed lnb and warmed it up inside and it worked until it got cold again. Has any one else had troubles with this???I am feeding 3 receivers a 420 RCA , a Phillips, and a old Toshiba. They have been real good boxes Thanks for the help
