I have been with dish for over 15 years, i have had a dish 500 and a 1000+. I was swithched to a 1000.4 when i upgraded to a 722k. Now today it is snowing and have lost signal several times due to snow on the dish. with the previous dish antenna's i never lost signal due to snow, have had to clean 3 times so far. Have other people that have had this 1000.4 antenna experienced the same issue? Is there something i can do to prevent snow build up? Thanks for any help.
