[QUOTE="Channel Hopper, post: 1083305, member: 175144"] I'm surprised they suggest a dedicated wifi antenna (looks like a Gabriel antenna design) when any parabolic reflector with a dipole cut to the right frequency and stuck at the focal point will work. I have a set of exhaust baffles for the motorcycle in the house (for MOT passes) consisting of threaded bar and 28mm washers at strategic points, which I suppose could be used once upscaled to provide the right band for reception. Similar to that pictured (MMDS detector with LO of 1838MHz) The longer it is the more directional it becomes, adding more washers and spacers. Chaparral made a triband corotor years ago that included an S-band dipole in the scalar rings, I'll dig it out from the shed at some point [/QUOTE]
