What is the appropriate balun ? 1:1 1:2 1:5 or others ? tnx


The feedpoint impedance of a 15m dipole at 10.1MHz will be reasonably
close to 50 ohms, so you want a 1:1 balun.


It depends on the feedline impedance. If 50 ohms, a 1:1 balun is
probably appropriate. If open-wire line, a tuner at the bottom is
probably best.
