My antenna is not resonant on any amateur band. It gets almost there
around 4.1MHz.
(SWR 1.8:1 or something) It's an unequal leg length variously bent
doublet made with whatever length of 30 gauge magnet wire I managed to
fling out into the trees on that particular occasion.

Approximately: one leg 60 feet long about 24 feet high at the feed,
about 35 feet high at the other end. The other leg about 50 feet long,
bent groundward at a point 35 feet up and 30 feet out with an almost
vertical descending portion.

The "feedline" is a slightly tapered open wire section of the same
magnet wire with more or less 1.25 inch spacing. It's only about 4
feet long.

The antenna tuner is hidden in a big blue wooden box on my balcony
directly under the antenna feed, so I don't need much of a run of
feedline. I set plants on it.

The length numbers are *very* approximate. I've paced out the
tree-balcony distance and also checked with google earth, but I figured
a tape measure might be a bit suspicious.

I actually have very little trouble tuning the antenna. I do have a
lot of noise and removing all I can of the conducted component would
serve me well, I think.

The imaginary part of these numbers seem a bit odd (oh no, only three
of them are odd--the rest are even). Is your antenna resonant on any
band?
I'm probably not well-versed in all the impedances an antenna/feedline
can take at the tuner, but would like to know what antenna and feedline
this is.
