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 "Cecil Moore" wrote in message ...

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? "John Smith" wrote in message ...

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...
