It's a multiple of a half wave on all those bands, which means the
feedpoint impedance is very high, typically 2,000 to 5,000 Ohms. A good
"all"?
If it were about 65 feet long, it could be a half wave on 40 CW, and a
full wave on 20 low phone, 1.5 wl on 15 high phone and 2 wavelengths on
10 FM. (The resonant frequency increases by a factor a little in
excess of the harmonic number.) However, even that doesn't explain how
it is supposed to work on 30, 17, and 12 meters or cover 10 CW.
You might as well call it an end fed random wire.
