It is for this reason the transmitter chassis is grounded and
separated from the radiator system which has it's own closed circuit
and where the potential is above that of true ground. In this way your
transmitting circuit does not have a ground loop which is the last
thing that you want.

i don't know where you get your radios, but in all of them here the coax
connector is connected to the transmitter chassis which also has a lug for
going to the safety ground.

Lightning tries to get to the true ground by the shortest route and
the requirement is for you to not be part of it's route, even if your
radio has to be the sacrificial lamb if you haven't pulled the plug.

there ain't no such thing as 'true ground', tis all relative.
