Abstract
A waveguide system that includes a plurality of waveguide sections, each taking the form of an elongated longitudinally extending tubular member having a substantially circular shaped wall in cross section which coaxially surrounds a longitudinal axis. The wall has a longitudinally extending trough portion extending radially inward toward the longitudinal axis. The trough portion is defined by a pair of circumferentially spaced wall portions extending inwardly and joined together by a connecting wall portion. The wall portions together define a ridge having an inner surface on the interior side of the wall and an outer surface on the exterior side of the wall. Each waveguide section has opposing ends with each end having a longitudinally extending peripheral lip at the ridge. The wall has at each said end an annular mounting flange extending essentially radially outward from the exterior side of the wall. A plurality of spaced apart fastening means interconnect the annular mounting flanges of adjoining waveguide sections together in such a manner that at least one of interconnecting means is located in trough portion.
