the double-eight antenna provides 14dBi and is simple to made (both 
wire and pcb version).
Check Stacking two of them 
should result to (theoretically) 17dBi.

Trevor's waveguide can be made of a flat thick (1.5mm) zinc slice 
(the way we make paper cubes from a plain paper), opening slots on 
it, and then fold and weld seams. With rectag. aluminum tubes man 
needs router to open slots. Flat thick zinc, you can just punch slots 
on to it.
