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

Matching 450 ohm ladder line into a short length of coax for use with an auto tuner. Works great with a 160 meter dipole. Should have done this years ago.

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.

I purchased this for an off center fed dipole project. This is a new antenna type for me so there was lots of experimentation, climbing ladders, changing leg lengths, etc. - all the normal new antenna stuff. Today, while doing soME more experimentation, one of the leads has become completely disconnected internally. My antenna legs were always connected to the eye bolts on each side so there was never any direct strain placed on the leads. Id have expected there to be some sort of internal strain relief so that this couldnt happen. Completely worthless to me now. Dont have the packaging so dont think Amazon will take it for return. EDIT: Contacted MFJ directly and they are replacing the balun. So, good review for customer service from them but Im leaving 2 stars because the balun did break after only about 2 weeks of use.

Simple device, works great, with a manual control antenna tuner I am able to get SWR in a range from 80 to 17 m with a 40 m wire dipole antenna in the attic.

Works well thx

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

MFJ is good quality.Worked good on ocf antenna.

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.
