The real and only way to make a 4/1 Guanella Current Balun, dual individually wound cores, if it uses a single core it is a voltage balun as it has one side directly connected to the rf socket earth connector. The Guanella current unit has 2 independent lines with tunable ferrite wound coils to balance the lines, it also offers substantial RF return choking which eliminates a 1/1 choke in the feedline.

Tunable chokes to balance the lines
