Actually, that isn't all correct.  SWR is an indication that your system
is interacting with something close to it.  My 80M 4-square had 1.7:1 SWR
in the NE and SW directions.  We detuned all my towers, and now it is
1.1:1 and the 4-square has much better pattern than before.

As for finding the resonant frequency of your system, that would be
determined by the minimum dumped power frequency, which is the point Merv
is making.
