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.
