"I ended up making an ally tube vertical 10M tall. The lower sections are double wall so it is self supporting but I will consider adding guys if wind sway gets too scary. I then added 12M of wire to the top that slopes down to a 5M mast on the corner of the block so I now have a sloping "inverted L." The wire length is solely based on the distance available. I have an earth stake but no radials as yet but plan to add some in the next few days.
It is obviously a non-resonate length but the internal antenna tuner (more correctly a transmission line matcher) allows me to use it on all bands 80-6m, and with an external tuner, on 160M. "
Are you feeding the coax inner conductor to the base of the tube directly or via an UN-UN ??
If UN-UN then ratio ??
