greetings marconi;

How can one operate a radio through the antenna without a feed line? Once the feed line is introduced, the cmc is introduced.  While some may have luck in their installations, others may be unlucky and can never tame the cmc.  Power amount being one variable that adds to the mix.  


Isolation is one of those things along with antenna height, feed line length, feed line routing, feed line grounding point and counter poise at feed line that may aid in controlling the cmc.


I hope this is what you are talking about.
