I didn't say a single thing about a "cosine law" either.

If anyone knows where to look in that book for information on such
I'd be obliged for the information.)

Information on inductively loaded antennas seems to be sadly lacking.
But I have found one in _Antennas_ by Kraus & Marhefka, third edition.
I trust that will be a good enough reference for everyone.

On page 823 under "23-13 TRAPS", what he says about traps is not relevant.
But what he says about traps on half their resonant frequency is absolutely
choice.

"At frequency F1, for which the dipole is 1/2WL long, the traps introduce
some inductance so that the resonant length of the dipole is reduced."

On the next page, the current distribution is shown for the trapped dipole
on 1/2 the trap's resonant frequency. Needless to say, it clearly shows
a current drop through the inductive trap.

And talking about phasing using coils: "A coil can also act as a 180 degree
phase shifter as in the collinear array of 4 in-phase 1/2WL elements in Fig.
23-21b. ... THE COIL MAY ALSO BE THOUGHT OF AS A COILED-UP 1/2WL ELEMENT."

Emphasis mine. Now you guys can stop pulling our legs and confess that it
was all a joke.
