Why than: "The ideal ground system forAM broadcasters comprises at least
120

buried copper or phosphor bronze radial wires at least one-quarter
wavelength long and a ground-screen in the immediate vicinity of the
tower. All the ground system components are bonded together, usually by
welding, brazing or using coin silversolder to help reduce corrosion".

Tell them that they are WRONG.

Hello again Szczepan
The answer to your question is in that Wikipedia article. Read the
"Radiation Pattern" paragraph.

If you can get ham radio textbooks in your country then you'd understand a
lot better by reading a textbook on aerials.
Try http://www.rsgbshop.org/acatalog/Onl...tennas_37.html
and www.arrl.org/shop/Antennas/

I haven't seen an answer from you to my question which asked:
"Are you discussing resonant or non-resonant aerials, please?"

Best wishes, Ian.
