My signal strength was down to 30 on both tuners in both utvs. I bypassed the multiswitch to determine it was either the lnb or the dish was misaligned. Since it started 3 hours into a rainstorm I was wondering if something might be blocking the signal to the dish.
Well, turns out my 7 year old lnb developed a crack in the round cup shaped translucent plastic cover. It was cracked on the side facing up and had filled 1/2 up with water. Luckily no shorting. Being cracked, it easily turned 180 degrees down and drained, returning my signal. Got some duct tape around it now while I hunt for a new lnb.
