The “REAL” GUANELLA CURRENT BALUN
High or low power TRUE Guanella 4/1 current baluns using 2, 4 or 6 cores. Superb matching.
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 and can be fitted with tunable ferrite wound coils to balance the lines if required, the Guanella BALUN also offers substantial RF return choking attenuation which eliminates a 1/1 choke at the antenna feed-point. A 1/1 choke can still be fitted at the Transmitter feed-point which will reduce noise picked up by the feed line.
