    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.

    Couldnt figure out why my OCF 80 meter dipole wasnt working. So I decided to change the balun, cant figure out why I had to, the old one was only 25+ years old. ( think I can get a refund?.....HI HI!) I put the mfj-913 in line....WOW! No tuner required for 80, 40 or 20 meters...Can now tune 160 through 10 meters!

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

    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.
