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

    Balun works fine with my 80-10 OCF Windom antenna.

    Yes its not 1kw but for a 100w radio it works perfectly fine and being so lightweight it didnt drag my OCF down since i have no way to support from the feed point, only pulled tight from the ends. So for my needs it was perfect.

    Excellent Balun - used for quick Field Day installation - worked perfectly . MFJ quality has become very good.

    This MFJ-913 works great on my 80,40,20 OCF but only up to 40 meters. The swr is great at 80 and 40, just a touch of tuning is needed at 20. But now my feed line is radiating on 80 meters after only a week of having it up and is causing rfi in the house. Im only running up to 100 watts. Probably just a quality issue im guessing.

    A very good 4:1 balun to match my 300 ohm balanced line feed.

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.
