[QUOTE="archive10, post: 925574"] My friend, I am 99% sure there is no booster that will help you get better reception when it rains. And this is not 100% purely because your setup may have some freak condition. But, you have to understand that it is NOT the absolute signal strength that is the prime challenge here; it is the difference between signal and noise. When it rains (or snows or whatever fom of precipitation you choose), the water in the atmosphere absorbs the microwaves, and thereby removes your signal. So the signal to noise ration goes down. Noise does not, as this stems from background radiation, electronic heat, and other local soures. (The satellite signal being NOT a local source). The only, and I repeat, ONLY way this can be improvd is to start with more signal to noise ratio. And the signal-to-noise can ONLY be improved with a larger dish. You also have to understand that your receiver contains an automatic gain cicuit, that will boost the signal as needed. No need for more boosting - it is pointless to add more electronics. I know you intensely want to deploy a signal amplifier just in case it might work (and we all might be wrong). But please save the money (and the time spent fiddling with cables) - it won't make nay difference. (In fact it may just make it worse - the added electronics just make more noise...) [/QUOTE]
