I have the issue someplace but could not put my hands on it. Just found it!

If you need a copy, I can scan and send it.

By putting an LC circuit somewhere in or close to the center of a vertical you get two resonances, one where the C-part act and increase the resonance and one where the L-part decreases the resonance frequency.
