Well, I dunno... I went through a long and painful process of trying to
find a point on my similarly loaded tower that would give 50 ohms when fed
with a shunt wire and a series capacitor. Never did. Finally, I added a
second capacitor for an omega-match configuration, and had a 1:1 match at
1830 in about 10 minutes.
