Marconi, I'm glad that that fixed the problem you were having.  You essentially made a makeshift inductor, which, like on an antenna, will change the electrical length of the outside of the feed line to a length that did not cause said problems.  I'm happy that it fixed your issue, but that is not a choke, however much it resembles one to some people.  What you did can be a two way street, in one installation it may fix a CMC issue, while in another doing that can actually cause a CMC issue that didn't exist before.  The difference between what you are talking about and a properly designed choke is the choke won't have the potential problem of adding CMC's to the feed line if it wasn't needed to begin with.
