Mike,

In the ones I'm familiar with, you can't mount an antenna above the hex. 
   The mounting flange from which all the spreaders emanate mounts to 
the mast.   Above this flange is the center post, which  has all the 
mounting lugs for the  wire connections, the coax connector, and at the 
very top is the eye bolt  to which all the  cords attach.  These cords 
  go to the spreader tips.

Of course, someone could have developed  a different way of doing things 
and forgot to tell me.

These are the antennas I'm kicking tires on. As for the Mosely SF-402A, it has a forward gain of 3.9DB and a front to back of 15DB. Get a 6DB forward gain average on the hex, pretty good performance.
