Dear Fausto, LF Group, Having the top loading wires as high up as possible is always best - greater height means higher radiation resistance and usually lower loss resistance, so that will boost your

Fausto, as the length of the line (20m) is only a very small part of the wavelength (less than 1% at 137kHz) the impedance does not matter too much. But after the variometer you will have a very high
