Why does Satellite not work in a rainstorm?

The signal is effectively reduced to the point where it is no longer locked onto the Astra 2D satellite, due to atmospheric conditions I guess. Happening here in Switz right now. Surprised it's happening back in blighty though, I'd have thought the satellite footprint was strong enough back there to handle a little cloud and a storm.

Rain absorbs some of the signal getting beamed down to you from the satellite, in much the same way as the energy in a microwave oven is converted into heat in the water molecules that it happens to meet on its travels. The actual signal level when compared to the noise level with digital satellite transmissions is not that huge and so it doesn't take much attenuation to put the signal down below the noise and then your box can't discriminate it from the noise, so you lose the picture. When you consider the very tiny amount of power the satellite transmits and the huge area of the earth this transmission is spread over it is a miracle it works at all, never mind when it is being attenuated by a rain storm.

Depends which transponder you are 'looking at'. You'll find different channels on different transponders have different levels of signal quality.
Most weather related problems are due to crappy equipment supplied by those arch a55holes SKYTV- "the television choice of imbeciles"

Strange how rain absorps the radio waves. Yet you can put a plastic bag over the LNB without any affect. (Plastic bag helps protect it from the elements - and old trick from yesteryear when they used to cost alot more and weren't as reliable against water ingress )

Cable used to suffer from bad weather too. As they too used to recieve the signal from the Astra satelites (as per sky) , prior to uplinking to the cable network.
There was a time with analogue cable (back when it was called Cable Midlands). The recieving centre wasn't far away from where we lived, and we suffered the same signal issues as with sattelite in heavy rain storms
