How do i make a 9 to 1 balun out of a 3/8 ferrite rod (Receiving only)


Take 3 pcs of wire, put little temporary tags on them to identify the ends,
wind them together on the core. Then wire them in series. Call one end
ground and the other end hot. Your high impedance terminals are the hot to
ground and your low Z terminals are one winding up from ground, and ground.
In other words your low Z is one winding and your high Z is all three
windings.
