I haven't been able to find out the proper placement of ferrite beads.
Are they placed ANYWHERE along the cable.
Ideally, they should be placed at a common-mode standing-
wave current antinode (maximum). Aren't you glad you asked?
Most hams install the choke at the most convenient
place. However, at the feedpoint of a one wavelength
dipole is not a good place.
A common place is at a BALanced to UNbalanced junction
where the choke can perform the balun function.
