is rain fade?
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:
1. Water in the atmosphere
2. Water on the dish and LNB
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
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
How long will it last?
One application of Rain Shield will last about a year when applied
How many applications per
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.
