What's the effect of fog on OTA? I'm 40 miles out with a DB8 and 125 ft run. Paid someone to put the antenna 10 ft up on the chimney this morning. Fox is 2 degrees off but all other stations are the same direction. However it appeared even though it was on the roof, I couldn't get in ch 64 and 67 in the high 80s like i did in the attic. My guess is the chimney was 5 ft to the right of the original spot inside and i guess that made the difference. But i didnt' want the hassle of a tripod. Anyway, after over 1 hour of struggling aiming the antenna 1 millimeter at a time, and trying a pre amp from the guy (turns out my regular amp was better anyways), I've now gotten fox to be solid mid 60s and channel 67 and 64 seem to be solid 68ish or 72 ish. If everything stays as is, i'll be thrilled as I can record solid 60 signals. But I was wondering if the dense fog helped or hurt the aiming this morning? If all the channels die tonight after the fog is gone, i'll scream lol.
