In all answers no clear information if your "black box" have the
earth/chassis/counterpoise.

Have you looked at any of the books I mentioned in an earlier posting,
please?

I know what is in the books. I do not know if your ""black box" have the
earth/chassis/counterpoise."

Good morning Szczepan.

I think we have a language problem here. The answers to your questions ARE
in the books that I mentioned. If these books are not available in your
native language then I can understand your difficulties.

I recommended the amateur radio books because they cater for people who have
no prior knowledge of radio and aerials.I still haven't seen an answer from
you to my question "Are you discussing resonant or non-resonant aerials,
please?".

Kindest regards, Ian.
