Identical current indication on a matched pair of thermocouple RF amp
meters do not necessarily mean the transmission is balanced as the
current magnitudes might be equal but the 180º phase difference isn't.
Roy explains this situation one page 4 of his paper /"Baluns: "//What
they do and how they do it//."/ that can be found at:

Yes. Got any recommendations on which to use? There are at least a couple of
schematics
and articles on home-built units on the web. What do you use?
I have a link-coupled home-brew balanced coupler I built many years ago which I
am going to
use with my "new" Vertical Vee-Beam antenna as soon as the Swainson's Hawk
family which
has taken up residence in my only support (a 110' tall Grand Fir Tree) leave
this fall.
So, I want to install a pair of RF ammeters to help me achieve balance.
