[TowerTalk] Fwd: effect of two wire antennas end to end

[Hans Hammarquist via TowerTalk]

A Windom with an open (ladder) line would also work. Sometimes you want to work without a tuner as some of us consider a tuner a PITA. (I love tuners myself. Have several of them and use them all the time.)

The greatest amount of interaction would be between the feedlines!

Why not ONE zepp antenna between the two towers and use open-wire  
feedline and a tuner?
