Pat Mulreany, WX7M, here in western Nevada, took a different approach.  He
assembled a 16-element 20-meter yagi on a 280-foot boom from which he
calculates 19 dB forward gain (I don't know whether it is dBi or dBd).

If you are wondering what he used for boom material, it is standard
agricultural irrigation pipe.  You can see a photo of it on this months CQ
magazine.  Now if he can just figure out how to rotate it!  :)

73, Dick
