Dick,
There is no way possible to answer your question because it
depends on the dielectric stress in the material. It would
depend on electric field strength and how it is distributed
even more than the material itself.
In almost any case I can think of, Plexiglas would be ok.
The only problem would be if you had Plexiglas for a
dielectric in a capacitor.
As for tests, how a material behaves at 2GHz generally has
little to do with anything at HF. You are not looking for
absorption at 2GHz. You are looking at LF performance. The
best thing you can do is try it, and odds are the Plexiglas
would be the last worry.
