I should just stay with the AD 91XG & make no changes? Higher gain preamp for weak UHFs?

I was just saying based on the TV fool plot you gave, NBC is not a station to plan on getting. On the other hand, KGO-TV RF 7 ABC should be possible to get with a Y10-7-13.
The RCA Preamp TVPREAMP1R is nice, I have one. It has surprisingly low noise for its price. I think it is as quiet or quieter than a HDP-269 and comparable to a 10G201 (of which I have both.)
I read about people asking about preamps and it seems what they do is not quite understood. A preamp takes whatever signal the antenna feeds it, adds some noise to it, and amplifies it. The amplified signal then can overcome losses in cables, splitters, ground blocks, poor termination of cables, filters, and possibly a noisy tuner in the TV. A super high gain preamp does nothing but add noise if there are no losses between the antenna and the TV. If a signal is going to be split, for a two way split, that is a 3 to 4 dB loss, so if a preamp adds less than 3 dB of noise, then the loss from the noise in the preamp versus the loss in a splitter without a preamp are roughly equal. If more than 2 splits are needed, a good low noise preamp will probably help.
The only reason to need a preamp with more than 22 dB of gain is if you expect than 22 dB of loss. That would be (at UHF) an 8 way split (12 dB of loss), and 250 feet of cable (10 dB of loss). The gain the TVPREAMP1R offers is sufficient for most “normal” installations. The other thing to watch with preamps is if they will overload.
You have a couple of close transmitters, but nothing screaming lout, but still, the RCA TVPREAMP1R seems to gracefully handle a high input signal.
Right now, looking at what has been discontinued in the line of preamps, the TVPREAMP1R is probably the best preamp out there for most installs.
