[QUOTE="Vipersan, post: 648656, member: 325666"] ..just as an addon to what I posted above .. The origional in line polariser was unusual insofaras ..it did not rotate a probe.. In actual fact it had a small motor driving a nylon gear external to the waveguide ..which in turn rotated a circular gear inside the wavegide. This circular gear was atached to series of linked plates in a line..which ran lengthways down the wavegide. one end of this series of linked plates being anchored. The first plate would rotate through 90 degrees dragging the other plates behind ..sequentialy.. The net effect was to form a twist in the wavegide pipe ..and thus rotate the signal through 90 degrees. Did you ever see one of these before ? rgds VS [/QUOTE]
