While KM1H and some other guys have told me that matching a loaded tower
is easy, and requires only "iterations" until you get it right, W1JZ has
always taken the position that you should leave the tower bare, except
for a single yagi on top.  Finding the exact right feedpoint is, in my
experience, a problem -- and I'm not sure I've found it yet.  The heart
of the problem is that it remains black magic.  No one has ever written
up a series of steps which, if followed, will ALWAYS result in a good
match and an efficient antenna.  If someone has written up such a
step-by-step procedure for loading a tower, I've never seen it -- BUT I'D
LOVE TO SEE IT! -- Fred K1VR
