Theoretically linear, but they should be considered to be a quarter wave vertical with some crap lying around in the nearfield. They don't have any gain, and they certainly don't work as yagis - in fact, they work better sideways! The can needs to be made of metal, and about 85mm in diameter. That will give you a belter of a wifi antenna. The threaded rod and washer idea is just stupid. Leave that off. Gordon _______________________________________________ Sent via [email protected].
