Team, Here is some information I just received from one of our VARs.  He's been struggling to get PMP320 gear registered.  This seems to solve a problem that many have had with registrations. Vernon,
  Two things, FCC has now added a new code for those antennas, it is D.  Also they recommend you set the Lower Center Freq to 3650 and the Upper Freg to 3675 when applying, that gives you the whole band to play with.
