I'm using a random length loop, probably about 200 feet fed with
450 ohm ladder line. The ladder line hangs about 18 inches from
my tower and I get good reports from all over. My advice, if you
have and idea, try it, if it works great. If not, back to the drawing
board

In general there is a magnetic/electric field between the conductors in
twinlead feed line.

Dave,

Just to clarify, is the 'magnetic/electric field' to which you refer
the same as saying 'electromagnetic field'? I am just trying to
clarify whether it is just how you expressed it or if you are making a
distinctive difference.

Thanks
Buck
