Dave:

The T-Match will still show a favor in signal launch because of the
imbalance of the gamma rods on one side, on a beam this could even be
manipulated to ones favor--not as likely on a monopole... just looking
for a way to completely balance the field pattern...
I just thought someone had most likely done something like this
before... if I don't hear of anyone, will shove some various sized
drain, stove pipe, soldered cans, etc. over a 1/2 monopole in place of
the gamma rod and check it out this weekend...

Warmest regards,
John
How can a T match have show a bias- it is balanced. Virtually all the


serious EME arrays use this matching technique and show the major lobe

dead
off the front.

Was that you I worked while mobile on 6 yesterday or the day before?
Sounds like the call I remember.

Hi Tom,
I knew the band was open because of 88-108 stations booming in, but my rotor
and remote antenna switch wires to the tower are temporarily disconnected
while we build a 180 ton rock wall behind the house. I'll be back on this
weekend.
