Fan Dipole V2 measurements order 10/80/15/40/6/20m

This is the second version of the fan dipole.

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.

In this second version the 6m and 10m wires are swapped. So the order is now:

  1. 10m
  2. 80m (wire to short, compensated with 80uH coil in one leg)
  3. 15m
  4. 40m
  5. 6m
  6. 20m
