If all four towers were used at one time, it would be called a dog-leg array
(a really fancy technical term whose derivation eludes me :-). However, WCAP
uses the three in-line towers at night and one of those three plus the one
that's not in line during the day, so I don't know the correct technical
term (simulated dog-leg array?).
