[Elecraft] wire antennas

[Stuart Rohre]

Mike and the group,
I am currently routing heavy duty 300 ohm twin lead from a 5/8 leg 20m 
antenna, thru a slot cut into some foam pipe insulation that acts as a panel 
in the bottom of a aluminum sash window.  The window has aluminum sill, and 
frame, and individual panes of glass with aluminum sub frames.  Cross the 
metal at right angle does not affect the normal operation of my B&W tuner, 
and I am using the internal balun of this tuner and getting normal loading, 
and good signal reports with only 20 watts SSB, from the rig I use.

If you cross at right angles and twist the feeder outside along its run, 
interaction with conductors is minimized and balance is preserved adequately 
for use with the tuner.
