Super twists are a compact alternative to twisted rigid waveguide tube. Machined from an aluminium billet, they provide a full band twist in the shortest possible length. Threaded holes in both flange faces facilitate quick, easy installation and a powder coated finish provides an environmentally resistant, long-lasting aesthetic finish. Grooved flanges are offered as standard - these can easily be mated with a similar grooved flange using the double height O-rings / gaskets found in the optional fixing kit. This simplifies both design and installation by eliminating the need to consider alternating grooved and plain flange interfaces.
