Does the radio have any coils in the front end? Like the old-time radios, a primary coil between the antenna and chassis ground. If it has coils, there is NO way for static electricity to build up beyond millivolts, since all is at DC ground.

Another way to accomplish the coil isolation would be to use a
1:1
50 ohm wideband transformer from Mini-Ckts lab. They are only a
couple dollars...
If you have a good parts box, you can wind one yourself as they are
very simple. The ARRL handbook can give you guidance if you are
not familiar with the technique. Simply a bifilar winding around a
small ferrite toroid.....

I'd also still use a couple of backtoback diodes, in parallel with
a
neon lamp. Couldn't hurt........ might help, once.......
