Like AC6LA I have no connection to the company, but I note that Danny
publishes complex Common-Mode impedance plots for his chokes; I believe
that's unique amongst manufacturers. I've checked a few of those
published plots, and his concatenated chokes produce some of the highest
CM impedances I've measured.

### heres the part I don’t get. Their 1:1 baluns, like their http://myantennas.com/wp/product/bl11w-5k/
don’t have any where near as high a CM Z ( resistive part)..as their CM line isolators..which all have
connectors on both ends. IE: http://myantennas.com/wp/product/cmc-230-5k/ or
http://myantennas.com/wp/product/cmc-130-3k/ .
### http://myantennas.com/wp/product/cmc-230-5k/ This one is a winner, and if used right at the
ant feed point, will not only do the job, it will no doubt drop the noise level on RX down a a bit.
##It appears that he has taken CM 1:1 chokes to a whole new level. Hats off to him.
