300 Watt 4:1 Current Balun
The MFJ is a 300 Watt true current baluns/antenna center insulators that transforms 200 ohms to 50 ohms. Transmission Line Transformer construction using 100 ohm characteristic impedance transmission line gives flat Metre response.
Large low permeability ferrite cores easily handle full power. SO, stainless steel hardware with direct 14 gauge stranded copper wire connection to antenna. Heavy duty weather housing. Measures 4¼ x 2 inch diameter.
