Many years ago I input all the frequencies and wavelengths into an Excel
spreadsheet to find a length of wire which would most closely be resonant
on
all amateur bands. As I recall 26.5 metres seemed to be an optimum length
when fed via an ATU. It isn't resonant on any amateur band, but most ATU's
will be able to tune it. It worked for me anyway 160m through to 10m. As
for
the performance, well it received well enough and obviously radiated
enough
of a signal to work 5000+ miles QRP.

I assume that the directionality was frequency-dependent. At higher
half-wave multiples, it would have been a beverage antenna, with strongest
signals off the end(s). Was that your experience? I'm getting ready to try
the same thing, although I don't quite have 26.5 meters to play with unless
I can string part of the wire onto my neighbor's property.
