Is my 'mission impossible' conclusion reasonable, or is there anything else you'd try to get KPIX/KQED/KTVU?
So now it gets a little more complex. "Managing the Multipath" rays.
Inch by inch, move the antenna down, down, down, for about 2-3 feet (Each way) for a total of around 6 feet elevation changes.
then up, up, up. And mark the antenna pole with a marking pen.You may notice signal peaks+ like every 16 inches, and signal nulls- too
So (easier with 2 people) and a cell phone. Tune 29 and find the elevation it locks on the best.
If that doesn't work, you may need to move the antenna (Not rotate) Left, Left, or Right, RightAllow time for buffering. (3 or so seconds) with each move
You will notice erratic UHF reception every 3 feet moved left, right, etc. That's what blocked reception from hills do.
Try a combo amp with 2.5db of noise or less. Like the 7777
