Rain fade on Domed (Covered) Systems
What is rain fade? Rain fade is signal degradation due to the interference of rain
droplets. Rain can affect performance as well as heavy water content thunder clouds.
Satellite frequencies have a great deal to do with degradation. C band satellite
frequencies have the best resistance to rain fade, KU band satellite frequencies have the
next best performance, and KA band frequencies are the most susceptible to rain fade.
Rain fade is also known as rain attenuation.
There are quiet a few examples of rain fade or degradation.
1. There is heavy rain (large droplets); it can block the uplink channels for
reception.
2. There is heavy rain that can block the receive signal to the satellite.
3. There is also moisture build-up on the dome or cover.
Unfortunately, all these examples are caused by acts of nature, that with a domed system
you will always experience all of the symptoms in varying degrees. There are things you
can do to reduce degradation.
1. If you live in Seattle, move to Arizona.
2. Get a big fan, point it towards the sky and blow the clouds away.
3. KEEP YOUR DOME CLEAN- Soap and water are the most efficient
methods. Some harsh or abrasive cleaners can be harmful to the outside of
the dome as well as signal interference. NOTE: Some types of cleaners as
well can eventually collect dirt. Be sure to select one that will work for
you.
4. After rain, wipe the water droplets off the Dome.
5. A bigger dish size and superior surface accuracy reduces rain fade
problems.
All domes on the market are susceptible to rain fade. MotoSAT’s Dome (aka Mini
Dome) as well as the T2 AutoMotion are the two domed satellite television systems that
have the lowest rain degradation on the market. Because of size and surface accuracy of
our dish, MotoSAT can offer the best performance in rain fade situations.
