But, yes, there will be radiation inside the insulation.


Air is an insulator.....


And yes there is radiation in the air as I said above but the air is not
infinitely thick.

What is better: bare metal or insulated metal?

To radiate what?


The radio waves.


Depends. Does "radio waves" mean NOT TV, NOT FM, NOT Cell Phone, NOT
Radar....?

To radiate what?


Your radio waves.

Like vacuum. But there are ions and free electrons.
In solid and liquid insulators no free electrons.


So, how can you tell?

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:

http://en.wikipedia.org/wiki/Permittivity

and in particular:

http://en.wikipedia.org/wiki/Permittivity#Lossy_medium

You are a babbling idiot.

What are you going to write? It is a very simple question:

I think I see where you're going with this Richard, but you must realize
by now that you're talking to a rock.

To put it another way, he wouldn't pass the Turing Test.
