> 3 dayWhen the balun arrived, it rattled inside. Disassembly showed that 2 nuts and a washer were floating loose inside. Actually trying to use this balun could have been disastrous. I will repair it just because as an electronic tech, thats what I do, and I enjoy the challenge. Basically, for most folks... buyer beware!

> 3 daySimple 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.

> 3 dayCouldnt 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!

> 3 dayI 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.

> 3 dayThe UHF output was misaligned and fixing that isnt easy as you cant remove screws or take this thing apart in any reasonable way. However, performance of this balun is pretty good with multiple wire HF configurations.
