To add TV to the cable would be $40 + $20 for the two additional converter boxes (three TVs).
There are no stations near RF 12. KGO VC 7 RF 7 has much longer wavelength and there are none higher on VHF-Hi. So KNTV is unusual and the amount of metal in the planes and how they land may not affect other wavelengths. It's the matching of the path to Bruno and the aircraft landing pattern.
If logging the breaks matches the numbers of landings at SFO then perhaps a major move of the antenna might help. Or pointing away from the direction of KNTV and Sutro. The landing path is almost exact ally what I showed
Airplanes merge into the landing pattern South of you and land on two runways at the same time (Weather permitting.) One after another, at a rapid rate.
I have been watching aircraft here since we first landed on the Moon. I am not a pilot but taking off and landing at SFO and SJC many times I have learned where the planes fly. And what happens when a strong cold front is passing. Taking off to the South West from SFO you keep wondering if Mt. San Bruno would be hit. They looked at Bruno for the location of the antennas but the FCC Said NO! Thus Sutro.
If airplanes are confirmed then perhaps a VHF-Hi antenna pointed away from Sam Bruno might
help with KNTV VC 11 RF 12. Then a UHF antenna pointed at Sutro could be added.
Note! The only allowed combination of antennas is One (1) VHF antenna and One (1) UHF antenna.
Multipath is one thing that NTSC analog signals were good with. A few ghosts, our minds subtract them. Picture breaking up or sound disappearing. We accepted it all. Now in the world of ATSC perfect or nothing we cannot.
Before you panic log the breakups for a few days and see if then match the busy times at SFO. Bring back your memory of analog KNTV on Bruno and what you saw before the antenna work on digital. It might be that lowering the VHF signal level might help. Chuck can help with that, I just am a mapping fool and very poor understanding multipath simpleton.
