Despite my windy QTH, I am seriously thinking of erecting a two element
30/40M quad on a 20' boom. The spreaders would, most likely, be in four
8' sections tapering from 2" diameter at the spider end to 1-1/4" at the
far end. If I were to fabricate my own spiders from, say, 1-1/2"
aluminum angle stock, I wonder what would be the optimum arm length to
obtain a balance between reasonable weight and strength. If anyone has
any practical experience with such a beast, I would appreciate hearing
