This may have already been covered here, but I couldn't find it. Do I need a VHF antenna for KGO ( 7.1)? I keep losing the signal. Last night I couldn't get it to come in for the life of me. My wife was NOT happy to miss the oscars. I have a nice UHF antenna (I forget what model, something like the Channel Master CM4220MHD) on our roof in Palo Alto. We get all other stations great, but KGO keeps coming and going. I have my antenna pointed at Sutro. Do I need to get adifferent antenna? Any suggestions?
