Hello Chris,
A mathematical (and practical) treatment of Multiple Tuning for vertical
antennas can be found in:
Radio Antenna Engineering
by Edmund Laport McGraw Hill NY 1952
pp. 38-43
This book is obviously out of print, but I could send you photocopies of
the relevant pages.

Hello André,
I still have to thank you for the article on the meander-antenna you sent me.
If it is not asked too much I would be interested in a copy of the Multiple
Tuning Antenna too.
Please give me your mail address, I will send you some USD as you have
already been spending some stamps on my account.
Regarding the meander-antenna : if you scale all the described antennas to
136kHz you still get 'monster-antennas'. But the fact that they manage to
increase the radiation resistance by a factor up to 20 (compared to an
simple vertical of the same height) is impressive. I would be more than
happy to get my radiation resistance up to some 100 milliohm instead of the
actual 45 millohm.
As soon as 'mowing-seazon' os over (october) I intend to do some tests with
various antennas. I will try to make some arrangements with Dick, PA0SE
(who is living about living about 120km from me and can measure accurate
fiedstrenght) to do some good (far-field) measurements on the different
antennas.
