I calculated the antenna using AutoEZ invoking EZNEC v6.0.9. Transmission line
calculations using TLDetails (previously referenced) and/or if you have Excel,
LineLoss.xls. All except for EZNEC available from AC6LA.com. Dan has a wealth
of information on his site, all of it fabulous documented.
Some editions of the ARRL Antenna Book had material on "Highly Reactive Loads",
shamelessly stolen from my correspondence with ARRL that also presented some of
this.
