Ted: My R7 (from 1992) performs very well. The 20 meter trap that is on mine is
u-shaped and not straight like the 17m trap. As for the tubing of 18" I can
only remember that some of the tubes are inserted into the other ends of
tubing. Perhaps the 2 inches are for the insertion at each end of the tube?
Did you purchase the antenna new or used? If the swr is intermittent I would
think that you might have something else besides alignment problems of the
traps.Bob n8wfl
