Copper pipe J-Poles would fair better... maybe even some small (1/4") tubing, 
and do exactly that - if you were to feed them horizontally.  Probably better 
suited for a vertical configuration.
You see my message to Stan on Quagi's?  Why not 4 J-poles (two driven, 
opposite of each other) two reflectors (same configuration) and yagi 
directors?  Put the whole thing on a 20' wooden boom...
