What will the auto tuner in that radio handle? I have an ICOM 7300 and it will handle 3 to 1 SWR and I think it will handle 10 to 1 with lower power in an emergency mode setting. But I use a manual tuner myself.

Ive heard people say that they can get their random wire antennas fed right into the g90 with little issue, I don't have the tech specs but Id assume its near 9 to 1 if their random wire is working, and that's made me curious to try the unit since I don't have any SDR yet. The unit only pumps out 20w max so thats probably a factor. On my Yaesu ft 891where I can run 100w easy I use an external LC tuner and a counterpoise to mitigate rf buildup on the chassis though.

That's actually pretty impressive if they can just feed a random wire directly into it and get it to transmit.

Its nominally called a 'random wire antenna' but the caveat is that it needs a tuner and if the wire length is too close to a length that makes it naturally resonate without a tuner, the antenna will not work.
