Open,Flash and clear
Yeah this is a multipath issue. I have one of if not the best antenna out there in the ch 4228. My signals come from the SE,S and SW. If I point directly south I can pick up all channels in the 90s, but then the SE and SW signals start to jump back and forth like crazy.Sometimes I can find a sweet spot that lats until a windy day comes along and then it takes a week or so using my rotor to find that sweet spot again. My Zenith set that has a built in tuner does not suffer from this problem though. I look forward to the series 3 to get my ATSC signals more reliably.
