CMC- Common Mode Choke as noise reducer video by AC0HF

I have been writing about great results I and many others had with the use of CMC- Common Mode Chokes as noise reducers when inserted in your coaxial lines. Many CMC’s  have been sold by and many positive reports came from happy customers. Please see the great video report  by AC0HF who demonstrated reduction of noise averaging a 3S-units (18dB).

We have received reports from few with results of 5 S-units  (30dB) and more of reduction of noise.
