[Elecraft] Antenna question

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! :>)
