After hearing reports of static discharge from the reflector to the 
boom, and doing an EZNEC analysis which, as expected, showed no 
difference in performance with the reflector connected or not, I decided 
to strap the reflector to the boom.  I used a short piece of soft 
aluminum cut in the shape of an L.  Clamped the bottom part of the L to 
the center of the reflector, bent the upper part of the L into a U 
shape, and fitted it under the reflector U-channel support, drilled a 
hole in the U channel and the strap, and secured it with a screw and 
nut.  I also added some Noalox to the joints.
