Ferrite balun 1.8 - 30Mhz
Take a length of coaxial cable (Coax) about 400mm long
Semplice choke balun 1:1 per QRP
The construction of a small 1: 1 choke balun
Choke balun 1:1
in this choke balun 1kw PEP(160m-10m)is used ferrite core from high voltage transformator from old television TESLA, 2x6 turns of RG8 mini sharmans
Construction of a 4:1 Current-Type Guanella Balun
My 4:1 current-type balun is wound on a FT-114-43 core
A simple impedance matching autotransformer for LF/MF
