So, if you made it 19% longer with some zig-zags, it would be resonant in
the middle of the cw band and no need for matching, just connect to coax. I
imagine it's fairly broad band being so close to the earth.

[referring to my original post]
A few minutes before the start of the ARRL 160m contest I decided to try
something I'd heard about. I took about 180 feet (55m) of wire and laid
it on the ground from my shack, across the backyard, around the back of
my garage and all the way down the edge of the driveway.
My 180' wire was resonant at about 2.2 mHz, where the SWR was around
1.4:1. Since signals not down all that much compared to the vertical, I am
sure that it would have worked as a transmitting antenna, and possibly
without a tuner if I had lengthened it a bit.
The interesting part is that it doesn't need to be straight to work. This
could be very useful in a real emergency.
