Fan Dipole measurements with BU-50

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 version the 20m wire is in the middle. So the order is:

  1. 60m (extended for 80m and 160m band)
  2. 20m
  3. 40m
Fan Dipole 160-20m wire order V1

Remarks 160m

  • unsuspected low impedance (maybe due to BU-50 1.8MHz lower limit)
