Chyba jednak x (zakładając zgodnie z tematem ze głownie chodzi o RHCP)
We tested the first antenna in a vertical set-up, with a metal boom. The SWR was not good at all. Conclusion: a metal boom will destroy the pattern of an '+'configuration. And even though I have a non-conductive boom, the preference will be for an 'X' configuration. After turning the antenna in horizontal position the SWR became good, with a optimum at 144.150 MHz, as expected from the calculations of DK7ZB.
