what do you mean by equilibrium?

I am not certain that I have got it all completely straight in my head, but
I have taken it to mean that all the elements making up the array and the
array itself are designed to be resonant about a particular frequency.

Hi Mike,

Then I take it by that response that the term equilibrium has no
meaning known to you in the context of antennas.

As
this type of antenna is intended for use with spread spectrum
communications,

Isn't that a bit of interpolation about spread spectrum? Arthur has,
to my knowledge, never used the term anywhere.

control over directivity is probably more of a consideration
than gain.

How do you distinguish directivity from gain?
