About MFJ-911 - 4:1 Balun/UnBalun - 1.8-30 Mhz, 300 W
The MFJ-911 is a true 4:1 current balun/unun that transforms 200 ohm balanced and unbalanced loads to 50 ohms. The response is amazingly flat from 160-10M because it is a true Transmission Line Transformer using 100 ohm characteristic impedance transmission line. Two low permeability ferrite cores are used to easily handle 300 Watts. Chance balanced to unbalanced operation with handy ground post. 2 x 4 x 1 inches.
