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

Nice product

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.

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.

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.

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

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!

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

Radio is toast because of defective balun

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.
