In this video I will show you how to build your own small but powerful 14dBi waveguide (cantenna) with a panel antenna replacing the more common monopole. The waveguide is constructed out of 1.5mm thick aluminium giving it an impressive front to back ratio. As such more of the RF power is focused forward in a 45 degree beamwidth.
