Topband: 'Hairpin' matching

I modeled my "Marconi T" antenna using EZNEC, got complex impedance parameters at feedpoint, plugged these into the L-network calculator that Tom mentions to find an L-network design, made an air-wound coil and found a suitable old air variable, and had 100% success getting a match exactly where the theory said it would be.

I was very impressed.

The excellent web site for calculating matching network values should have
been: 

http://home.sandiego.edu/~ekim/e194rfs01/jwmatcher/matcher2.html 

not the one I posted yesterday.
