This balun is capable of 1500 Watts SSB and 200 Watts CW or continuous duty mode.
The RadioWavz 4:1 Air Core Voltage BALUN is a Ruthroff 4:1 voltage BALUN it has become a very popular BALUN, and can be used with both floating and symmetrical loads without modification. Designed to handle its rated power with a low standing wave radio (SWR). It has 4 to 1 impedance ratio. Because of its air core it has the highest voltage break down ratings in its design class. 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. 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.
