> 24 hourThe 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.

> 24 hourMatching 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.

> 24 hourI 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.

> 24 hourUsed 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.
