This is the first attempt for the fan dipole.
Measurements (SWR, impedance) after quick tuning of dipole wires to give a first impression. Not all dips on frequencies where I want them to be...
Order of dipole wires top down
Most Fan Dipoles have a low to high band wire order (top-down). This might be the best solution, but I experimented changing the order. Putting higher frequencies between lower frequencies. Results shown below have this order:
- 80m (wire to short, compensated with 80uH coil in one leg)
It looks that 10m between 40m and 20m isn't a good order. As they are harmonics there is to much mutual influence. I will try swapping the 6m and 10m wires.
- unsuspected low impedance (maybe due to BU-55 3MHz lower limit)
- unsuspected small bandwidth
