[QUOTE="Analoguesat, post: 415342, member: 176362"] Water & water vapour is an excellent absorber for the microwave frequencies radiated by the satellites (around 12GHz) Hence a thundercloud heavily laden with rain but out to your south east can interrupt the signals even if its not actually raining at your own location. Snow on the dish is just frozen water so it will absorb signals bouncing off the dish. Remember the satellites are not transmitting high power signals. The signals radiated from the birds have the effective power of a lightbulb, so it doesnt take much to knock out the signal [/QUOTE]
