You might need to do the GH with NARODS for PBS.

I'm considering getting either a cheap HDHomeRun or perhaps a Hauppauge TV tuner. These include signal meter, signal quality, and symbol quality information that are provided by GUIs / phone apps. Curious if others out there have gone this route and what signal information they've been able to use to their advantage.

I compared the two. Both work, but I prefer the HDHR.
Here is a calibration chart for the HDHR. 100% SS is 0 dBmV = -48.8 dBm. Actually it's calibrated in the factory for 60 dBuV = 0 dBmV. Antenna installers and cable guys in other countries use dBuV instead of dBmV.
Tuners can handle much stronger signals.

I'm currently in contact with Tablo support to see why I'm getting pixelation and failed recordings. I asked about their device providing real-time diag info. They said their engineers are investigating supplying this info, but there is nothing definite at this point.

I wonder if the Tablo tuner is as good as a TV tuner, especially with multipath caused by the trees. If you made a side by side comparison, you might need a low gain preamp before splitting; 100 ft of coax acts like a 5 dB attenuator for UHF. If you mount a preamp at the antenna, it should be a medium gain preamp resistant to overload.
