MFJ Enterprises Original MFJ-913 Balun 4:1 Current 300 Watts

Great product and service

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.

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.

I cant really review this product since its sitting in my electronics junk box (term used for parts bin in amateur radio). I will eventually use with some antenna building project and after several months usage give and updated report.

Excellent product fast delivery, using on off center fed 40m dipole. Excellent swr in all expected bands

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.
