Default 50Mhz Antenna Conundrum

...
Interestingly, I am able to put out a signal on 6m using a fan
dipole designed to work from 20 through 10m. Today I got a report of
5-7 over a 1600 km path. The antenna design can be seen at
http://www.radiowymsey.org/FanDipole/FanDipole.gif .

As far as I can see none of the dipoles resonate on 6m - the 40m
dipole would if it was straight dipole with no loading coils. I
guess one of the dipoles has an odd multiple near enough.

The fan dipole goes into a 50 MHz LPF and then the ICOM 703 ATU. I
wonder if anyone has an insight into how this antenna is working on 6m.


I would not be surprised if its also works on 2 meters as well.
I would think a fan dipole would operate similar to a discone.
But the explanation of how it works is simple : its magic. (fm to some)
