you can make a simple common mode choke and do a before and after to see
the relative change..if any
I haven't read the link, but common mode current follows the behavior of
the feedline as an antenna, so common mode current distribution along
the feedline will vary as with a piece of wire having the dielectric
properties and dimensions of the feedline, and connected as the feedline
is. In other words, that feedline is part of the antenna.
So the obvious question is, how many measurements along that feedline
are you willing to make? :)
