balun spec depending on coax impedance
Charly wrote: Dear all, Usualy, people use 9:1 balun to connect a wire or dipole antenna to a 50 ohm coax. If I use a basic TV coax (75 ohms) I suspect I will need a 6:1 balun instead. If so, how many turns of wire should I use for primary and secondary windings ? I don't know the impendance of the antenna connection of my radios (ATS 909 + ICF SW100), so I intend to give a try with the coax I have in hand. http://www.dxing.info/equipment/impe...ing_bryant.pdf http://members.aol.com/DXerCapeCod/z_transformers.pdf dxAce Michigan USA |
