A T-match is balanced because it is right+left gamma
matches, i.e. gamma rods on both sides with two equal
series caps (or tube caps).

Cecil:

Sorry, didn't mean that sort "balance"--as in a balanced antenna... you
are right to make me be more specific...

....rather, I mean in the radiated rf field pattern of the antenna
itself--because the T-Match is only on one side of the driven
element--the radiation will not be completely circular (as in a
vertical)--and will begin formation of a stronger pattern in one
direction over all other directions on a compass, this is in reference
to a vertical monopole, but still would be in effect in a horizontal
version, in affecting a stronger pattern in one direction.... (and of
course, there is no such thing as a "perfect" pattern, just degrees of
more or less.)

Warmest regards,
John

but a vertical monopole about 1/4 wave long doesn't even need a matching
system in most cases... unless you are a real perfectionist. just what are
you trying to build here anyway?

Dave:

I had mentioned 1/2 wave monopole above--right now I am in the "1/2 wave
vertical monopole period of life"... grin... freq 10 meter on up...

Warmest regards,
John
