?Best tribander with 17 ft turn radius?

[OOPDAVID@ubvms.cc.buffalo.edu (D.RODMAN)]

We are thinking of putting another antenna on one of our towers for
the "multiplier" station to use.  The guy configuration will interfere
if the turning radius is much over 17-18 ft.  Any recommendations from
the group on what to choose or avoid?  Should be a tribander, of course.
