What is rain fade?
Sometimes heavy rain and snow can have a negative effect on satellite signal reception making the digital picture freeze, pixel or go out altogether. This loss of signal is commonly referred to as “rain fade” or signal attenuation. Satellite television reception is affected by two factors:
To prevent loss of picture due to attenuation, satellite service providers transmit signals down with extra power in areas where it rains frequently. This extra power is called the rain fade margin. In many cases, the loss of signal strength due to rain is not more than the rain fade margin, so you can still be watching TV when it rains. You lose picture when there is enough water in the atmosphere to completely block the signal, or more likely when the signal loss caused by a combination of water in the atmosphere and water on the dish and LNB exceed the rain fade margin.
How does Rain Shield prevent rain fade?
King’s Rain Shield eliminates the negative effects of rain and snow on the dish and LNB. While it does not prevent the reduction in signal due to excessive water in the atmosphere, it prevents rain on the dish and LNB from dropping the signal any further. In other words, when you eliminate the effects of water on the dish and LNB, the rain fade margin only needs to overcome the loss of signal in the atmosphere. It is very seldom that water in the atmosphere alone is enough to make you lose TV picture.
Snow has a similar effect on satellite signal when it starts to melt. Water or melting snow on the dish and LNB cause signal loss much the same as rain will. Without King’s Rain Shield, wet snow can stick to the dish and LNB. When the snow melts, the resulting water will run off in sheets that cause signal strength to be reduced. With King’s Rain Shield applied, snow and water will not stick to the dish and LNB. Water just rolls off in balls rather than spreading in wide sheets and therefore does not have any negative effect on signal reception.
How long will it last?
One application of Rain Shield will last about a year when applied as directed
How many applications per can?
Each 5 oz. can provides 4-7 applications on average. Customers in climates where wet snow is common will want to apply a thicker coat of Rain Shield on the dish, LNB and LNB arm to prevent snow buildup. In areas where snow is not expected, a thinner coat can be applied.
How is this different than other stuff I’ve tried?
Satellite installers have tried just about everything imaginable to prevent rain and snow from causing signal loss. While vegetable sprays and lubricants offer modest protection from snow buildup on the dish, the greasy surface attracts dirt and bugs, discolors the dish and eventually does more harm than good. Other rain repellants work on glass but will harm the plastic LNB lens. Dish covers made of waterproof materials work in certain types of weather conditions but not others. Only King’s Rain Shield works equally well in all types of weather. It’s also self cleaning, so you don’t need to worry about negatively changing the appearance of the dish.
How to apply?
Apply ONLY when the temperature is between 50 and 110F.
Clean the LNB lens and DISH with water (no soap) to remove all dirt.....
Thoroughly dry surfaces.......
Shake can for 10 seconds.
Spray the LNB lens.............. Spray the dish in the same manner.
Best to use it on both the LNBF and the dish as per the manufactures instructions for the best results.
