Satellite dishes are now commonplace in many parts of the world, but in order to work properly both the dish and the LNB (Low Noise Block) must be free of any obstructions. The LNB is the rectangular piece of equipment with a round clear plastic end that points toward the satellite dish. Leaves falling from nearby trees, sleet, ice and snow are all capable of interfering with satellite dish reception.
Things You'll Need
- At least two dry towels
- De-icer liquid
- Spray bottle
Power off the satellite receiver. This is the unit near your TV inside your home.
If your satellite dish is located on your roof, you will most likely need a ladder to access the roof. Place the ladder firmly on the ground and at a 20-degree angle away from the home. Do not point the ladder so it is completely parallel with the side of the home. Your weight (even if you are slim) will cause the ladder to fall backward as you ascend. Severe injury or death can result. Most newer ladders will have a sticker on one side showing detailed placement instructions. Follow these instructions meticulously. Ideally, have someone hold the ladder firmly while you climb. Also, use utmost caution when walking on the roof.
Once you are in front of the satellite dish, wipe it down with a dry cloth if water has accumulated on the dish or the LNB. Most satellite dishes are coated with waterproof material, but this material can wear off over time.
In the fall season, leaves from nearby trees can collect on the dish. Remove these either by hand or with a dry cloth. Also make sure no leaves have collected on the LNB.
If you live in an area that receives snow, ice or sleet, treat the satellite dish with de-icer liquid before the first storm. Many de-icer brands can be purchased with a spray bottle. Other brands may be purchased in a plastic jug, in which case you will have to pour the liquid into an empty spray bottle. In either case, spray the de-icer liquid onto the satellite dish. This will prevent snow, sleet and ice from sticking to the satellite dish.
If you have already experienced a severe weather storm, it is still relatively easy to remove ice, snow and sleet from the satellite dish. Spray WD-40 (WD stands for "water displacement"), silicon lubricants or oven cleaner (e.g., Pam, Easy-Off, etc.) directly on the snow, ice or sleet that is on the satellite dish or LNB. The frozen material should slide off within minutes.
Use a towel to wipe the satellite dish and LNB dry.

Tips & Warnings
- Do not use a pressure washer to spray off your satellite dish. The force of the water could jar your dish out of place, and a repair technician will have to be called to realign your dish with the satellite in space. You will likely incur the expense of having the technician come out to your home.
- Make sure the power is off before you touch the dish. The electric cords that connect the LNB to your home could be live, and you could be shocked. Use extreme caution when climbing a ladder to reach a satellite dish on a roof. If possible, have a friend or family member hold the ladder firm while you climb. Use extreme caution when walking on the roof. Roof tiles will be especially slippery after severe weather events. Work with a partner, and do not walk on a roof that still has snow, ice or sleet on it.
