[Antennas] Cubical Quad Question

[C.Whitaker]

You can't.  The best you can do is to come up the
pecking order that lets you leave the loops alone,
and tune each one of them in the proper order. 
You'll learn whether to tune the smaller ones first,
or the larger ones first, or something like that.
Be sure to sift through the advice you get.
