Do you know,at least roughly,the complex feeding impedance at the point where the line (ladder od coax) is attached to the variometer? Then we could calculate the losses for coax and ladder line. I e

Fausto, You can do that but you should place the ladder line between ground and the "cold" end of the main coil. Otherwise you'll have several kV in the shack and lower the radiation resistance stron

Thanks you Rik and Stefan for answer, of course I connect one wire of the ladder line at the ground just under the antenna and the same wire to the "cold" end of the variometer, the other wire frome

Hello, A question for RF expert: you think that i can connect a Marconi antenna and relative gound system to the variometer with a high impedance ladder line? This because i need to have all the tuni
