In the Dutch Magazine "Radio-Nieuws"of 1 April 1925 I found a treatment of
the multiple tuned antenna by Ir. (later Prof.)  Huijdts. It confirms what
Rik, ON7YD, expected: In a multiple tuned antenna with N radiators each one
has a loading coil of N times the selfinductance of the coil for a single

radiator.

Simulation with ELNEC confirms this in general: Not exactly N
times higher but somewhat higher, increasing with N. If mistuned
at one leg only this leg will degenerate to a loop antenna (via
earth, side fed) and the whole system will be a fine dummy or
cloud burner at best.
