If this uses one of those 1/8" mono headphone connectors for the stock user RF connection you can buy a F-type coax to 1/8" headphone jack style antenna connector and connect the coax to the factory user antenna hookup without the balun, and that would likely block interference.
It doesn't have one of those 1/8" jack antenna inputs. It's only the screw terminals on the back unfortunately.

I guess I could try to figure out how to replicate the capacitor scheme, but I'd have to make sure I kept the impedance at 75ohms, and I need to figure out what those resistors across the decoupling capacitors are. There is no part number for them at all. I guess it could just be a board trace or something? Maybe it's 300 Ohms?

Ah yes, the service manual calls them "component combination" CR101 and CR102, and describes them as "antenna isolation"
