    MFJ makes a good Balun. I used mine for a homemade Off Center fed. Does the job

    Matching 450 ohm ladder line into a short length of coax for use with an auto tuner. Works great with a 160 meter dipole. Should have done this years ago.

    Used this to build an OCF dipole. 90 feet one way and 45 feet the other way. Hooked to my tuner, I can tune 10 meters to 80 meters with no problems. Works fine on 100 watts SSB. Farthest Ive talked is Russia - 8000 miles away.

    I purchased this for an off center fed dipole project. This is a new antenna type for me so there was lots of experimentation, climbing ladders, changing leg lengths, etc. - all the normal new antenna stuff. Today, while doing soME more experimentation, one of the leads has become completely disconnected internally. My antenna legs were always connected to the eye bolts on each side so there was never any direct strain placed on the leads. Id have expected there to be some sort of internal strain relief so that this couldnt happen. Completely worthless to me now. Dont have the packaging so dont think Amazon will take it for return. EDIT: Contacted MFJ directly and they are replacing the balun. So, good review for customer service from them but Im leaving 2 stars because the balun did break after only about 2 weeks of use.

    It does what it is supposed do!. used it for a multi-band home brew dipole.

The MFJ-913 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 160-10 Meter response. Large low permeability ferrite cores easily handle full power. SO-239, stainless steel hardware with direct 14 gauge stranded copper wire connection to antenna. Heavy duty weather housing. Measures 4¼ x 2 inch diameter.
