The RadioWavz Air Core bifilar Dual Core BALUN is the Guanella 4:1 current BALUN. Designed to handle full legal power with a low standing wave radio (SWR). It has 4 to 1 impedance ratio. Two transmission lines are connected in parallel at the low impedance side and in series at the high impedance end. Making for a more balanced and favorable match. The Ferrite core provides for a more efficient transformation. Frequency Coverage: 1.8 to 50 MHz. Good for matching a 200 Ohm load to a 50 Ohm load, or 300 Ohm load to a 75 Ohm load. The 4:1 BALUN is a good match for feeding an Off-Center-Fed antenna and performs well feeding an open wire transmission line.
