  Ron, Colyn, Craig,
  I have the 9900BX in my L4P and many hours of flight time with it. I
  violated some of their rules because I refused to put the top antenna on the
  outside
  (Very UnSexy). Ryan told me it wouldn't work mounted in the inside of  the
  tail on my aluminum plate, with an UPS GPS antenna and a WSI antenna. I can
  tell you that I have had traffic at 12 o'clock with holding 1000 ft below 
 me
or
  climbing through my altitude and I could watch there distance and altitude
  on
  the TCAD coincide with there alt. hold instructions or by watching them 
climb
  through 0 altitude right in front of me. My bottom antenna is mounted
  between my  gear doors on the outside and it is putting out two Horizontal
lobes one
  to  each side, while the top antenna its putting out two horizontal lobes 
for
  and  aft. The inherent problem is that at the 45* points of the 360* you get
  the lob  interfacing and very often you see two targets at the same distance
  but  shadowed at the 45*. Ryan tells me that this is normal and you do get
use
  to it  and can easily tell the difference. I don't think it has anything to
do
  with the  antenna placement.
For the Legacy, I know you can't put it in the tail like mine and the
  wingtip doesn't sound like a good idea, so I would consider putting it on 
top
of
  the glareshield in the center of the windshield even if it is close to other
  
  antennas.
  Good Luck,
