I'll second Richard Harrison's recommendation of King, Mimno and Wing.
King wrote the "Antennas" chapter, and I especially like his careful
wording that makes the premises on which the rest is built crystal
clear.

I'd also recommend an article that appeared in the April and May 1977
issues of "Ham Radio" magazine. It's "The Antenna-Transmission Line
Analog" by Joseph Boyer. It's good for understanding impedances along
linear wire antennas (dipoles, and verticals fed against ground planes,
for example); if you digest it, you should be able to do an accurate
back-of-the-envelope calculation for a loading coil to resonate a short
antenna, placed any reasonable place along the antenna, for example.
It starts with a view about how fields are developed in the vicinity of
a linear antenna. It can be a bit difficult to find, but I've been
known to send scans or photocopies of it...

Cheers,
Tom
