[TowerTalk] 40-10 meter wire antenna

[Edward Mccann]

No, don't think of a second balun. Think of a Common Mode Choke. In fact think of two of them; one after the 4:1 Balun at Feed Point ( 50 Ohm coax to approx 200 Ohm Impedance at feedpoint; and a second choke at the shack end of the coax

More on this at Windom Yahoo Group, or at ON4AA Serge website.
