I thoroughly agree with Guy, well described, and this was my work-
around. I used an open wire feed line to my 160 inverted "L." It
worked great through a tuner on 80 and 40 but as Guy stated it is a
low z feed on 160 and the open wire concept is out the window on
that band. I installed a relay at the feed point and switched feed
lines. Open wire and the tuner on 80/40/30 (Yes, it works darn well
on 30 too!) was switched in and then coax feed switched in for 160.
