[QUOTE="Piggie, post: 33034, member: 2941"]I tried an Insignia, DTVPal Plus, Toshiba TV, Ölevia TV. Not a bit of difference. I had the problem constantly on ch 31 and ch 36 my two strongest signals with a CM4221A. I replaced it with a Radio Shack U-75R and bingo problem solved. It has less gain and dropped my quality meter about 5 points on all UHF channels, but it is steady as a rock on windy days, dry or wet leaves. I changed it before the analog cut off and it was clearly much better on wind leaf driven multipath. The U-75R has a 47 degree beam width, so it's not a long boom, but had the front to side to solve wind leaf branch driven multipath. There is quite a bit of information on this forum if you look about Mobile DTV.[/QUOTE]
