Greater than one weekWhen 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 dayThis 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.
