Folded Dipole Calculator

The impedance of this antenna is around 300 ohm, so you may want to use a transformer or a 1/4 long piece of 120 ohm coaxial cable to match this impedance to 50 ohm

The self-inductances are calculated
A variometer consists usually of two coaxial coils, connected in series, where the coils relative position can be varied in some way
