 I have the Trafficscope VRX in my Glasair and it works great.  It has
 shown me traffic that I previously hadn't seen.  I have it wired into
 my audio system and the voice warnings are great.  It is panel
 mounted, and I have an external Comant blade antenna mounted under the
 right wing.  I can't comment on how it works sitting on the dash with
 the little antenna, as I have always had mine mounted in its current
 configuration.
