I'm surprised there isn't a mechanism for the link peer to report the SNR to the sender from its perspective. I've had the same issue without any antenna troubles - Mac would constantly connect to the 5GHz network and struggle to send any packets out, yet the displayed signal strength was good. It turns out it was able to "hear" the AP just fine, but the AP had trouble hearing back, yet somehow there's no feedback mechanism for it to know.

A kind of SNR ping seems like it would make a lot of sense. I don’t know enough about radios but anybody know why that doesn’t exist?

  Wifi 6 has all sorts of active sensing stuff for spatial frequency reuse, but GP didn't say what generation of wifi equipment was being used.

  The industrial (non-wifi) radios I use at work have a signal/noise ping function. Its very useful.
