KGO real channel 7 / virtual channel 7 it's the same. At 44 NM (dB) is a good strong signal. Of the VHF High Channels 7 thru 13 , channels 7 and 9 have more problems with multipath and other interference , too much multipath makes the digital tuner not read the signal correctly. I have explained multipath over and over. You will find a ton of information about Tv multipath on the internet. If you have not done so , then connect a FM filter to reduce any interfering FM radio multipath and harmonics. Try raising and lowering the antenna , try turning the antenna some to the left and right. KTVJ real channel 4 might not be transmitting now. So you could use a highly directive channel 7 thru 69 antenna , Winegard HD7698P in a effort to get KGO. However you can also use a highly directive HD8200P all channel antenna in case KTVJ 4 goes back on the air. However as I said before you might loose some channels because the antenna is too directive , and this means going to a 2 antenna system to get the lost channels back. If it were me I would cross my fingers and go with the HD8200P. And if it does not work , then will have one antenna of 2 antenna systems I will be connecting. And if it's a 2 antenna system in your situation then the 2 antennas Can Not be connected together on one coax. It must be 2 Separate Antenna systems and splitters and coax with remote control A/B antenna switches at each Tv location.
