When we had our place in Silver Springs, NV, our 40-meter 4-square, with
an excellent radial system, was killer. I cannot imagine anything short
of a full-size 2, possibly 3, element yagi up at least 70 feet even
coming close. I would think it would take the 3-element yagi to even
approach the F/B ratio of the 4-square.
On the beach works *real* well. Any antenna we tried at Ballenita,
Ecuador, worked great. The QTH was roughly 10-meters inland from
high-tide! :>)
