MFJ-919 4:1 Current Balun 1.5 KW
The MFJ-919 is a 1500 Watt true current balun/antenna center insulator that transforms 200 ohms to 50 ohms. Transmission Line Transformer construction using 100 ohm characteristic impedance transmission line gives flat 160-10 Meter response. Large low permeability ferrite cores easily handle full legal power. SO-239 input, stainless steel hardware with direct 14 gauge stranded copper wire connection to antenna leads. Heavy duty, long lasting weather housing. Measures 3½ x 3½ x 2½ inches.
