Pete,
Find a copy of May, 1975 Ham Radio magazine and check out the article
titled
"How to Design Shunt-feed Systems for Grounded Vertical Radiators" by
John
True,
W4OQ.  I do not think there has ever been a better "how to" article
written
about
tower matching.
73, Good Luck

This is my ignorant question for today -- with only an antenna analyzer,
how can I determine the resonant frequency of my tower?  I plan to
attach a
first-attempt at shunt feed at about the 30-foot level, with 30-inch
spacing from the tower.  Can I tell from the analyzer reading at the
bottom
of that shunt wire where the tower is resonant?  Do I need to put the
series capacitance in before attempting the measurement?  Or is it all
fruitless?

Clearly my education was neglected or I'd know the answer, so thanks for
your help and patience.

73, Pete N4ZR
