Your radio waves.


To radiate what?

Glass is an insulator but it is transparent for the light frequencies.

Does exist an insulation (reasonably thick) which is not transparent for the
radio-amateur frequencies?

You obviously do not know that the amateur frequencies start at 1.8 MHz
and include everything above 300 GHz.

Within that range of frequencies, there are lots of materials that are
"insulators" that have large dielectric losses.

See:

and in particular:

You are a babbling idiot.
