[QUOTE="PaulR, post: 415321, member: 176256"] I disagree. It is mostly the water vapour and water particles (rain) in the atmosphere which absorb the signal. It is a similar effect to that of a microwave oven. The radio waves are absorbed by water molecules and raise its energy state (temperature). You'd be hard pressed to to measure the temperature rise from a satellite (hundreds of watts over thousands of miles) compared to a microwave oven (kilowatts over inches) but it's there. [/QUOTE]
