    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.

    The 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.

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

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