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.

Something doesn't seem right with that.... Care to post the math? Not
saying you're wrong, and I'd check it myself, but I'm otherwise occupied
this evening.

A 130' dipole, 60' high on 160 has a feed point Z of ~4.5 -j1200. One
hundred feet of Wireman 553 (typical ladderline) will transform this
to ~7.5 +j16 at the input. The total loss in this "low-loss" line is
over 12 dB.
