    I own 2 of these. One is the feed point for a 4 band fan dipole. The other feeds a an end fed Zepp style wire antenna like this: https://images.duckduckgo.com/iu/?u=http%3A%2F%2Fve3clq.files.wordpress.com%2F2011%2F01%2Fw3edpverticalmodel2.jpg&f=1 I could not build a current balun for much less money than these cost shipped.

    It appears to work OK, and I did not have to return it for repair, if you know what I mean..

    Works as expected on an attic mounted OCF dipole. Though stuffing 135ft of wire into an average size attic doesnt happen without a fight, and the requisite SWR is pretty high on bands the antenna should be resonant on.

    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.

    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.

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

    This will be used on a future antenna build.

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.
