Brush snow and frost off the TV dish with a broom if the dish is within reach. Some dishes are mounted on short poles or balconies, making them accessible.
Place a cover on the dish. Some companies sell slip-on covers made specifically to protect satellite dishes from snow and ice. Get referrals for reputable dealers from friends and neighbors who have satellite dish systems. Or, call your satellite programming provider for referrals. Place the cover on the dish by following the instructions included with the cover.
Purchase a heater for the dish. Some companies offer small, plug-in heaters that warm dishes just enough to keep ice and snow from accumulating. Ask neighbors and satellite programming providers for referrals. Hook up the heater by referring to the instructions accompanying the heater.
