RADIOWAVZ B14CA

4:1 Bifilar Air Current Balun

 This balun is capable of 1500 Watts SSB and 200 Watts CW or continuous duty mode.

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 Air core BALUN won’t saturate like the ferrite-core and, unlike ferrite-core wire-wound BALUNs, single-layer wound BALUNs almost never have insulation breakdown problems. This BALUN is rated for Full legal power. Frequency Coverage: 1.8 to 30 MHz. Good for matching a 200 Ohm load to a 50 Ohm load, or 300 Ohm load to a 75 Ohm load. A 4:1 BALUN is a good match for feeding an Off-Center-Fed antenna and performs well feeding an open wire transmission line.
