The only thing that is better than one Crosshair™ Xtreme is two of them.  The Dual Crosshair XTreme Antenna for Fatshark Dominator/Walksnail Avatar HD Goggles combines 2 Crosshair™ Xtreme antennas in a single form factor for long range HD flying.  Mounting directly to the Fatshark Dominator/Walksnail Avatar HD Goggles via the RPSMA connector, makes installation a breeze.  Just screw the RPSMA connectors in and enjoy the benefits of a long range antenna system with full field coverage.
