[QUOTE="Fisty McB, post: 934676, member: 389824"] Just did a non-scientific test on an in-progress new multi-lnb set up I'm trying which currently has five different LNBs set up on a 97cm dish centred at 16E with LNBs at 13, 16, 19, 23.5 & 28.2E (additional LNBs to the west planned, rain continuously stopping play here!) About 30 mins after rain stopped, I dried the dish face - then with each satellite position I took a measurement of the SNR on a channel , then went outside wiped the rain drops off the face of the LNB and retook a measurement. Across the five satellites there was a difference between 0.4 to 1.0db in gain between a LNB with a "wet" face and when it dried. Seems that there could be more to this theory that I originally thought, and could mean the difference in some fringe areas in reducing break up of some services at least in certain weather conditions.
