<p>The only thing that is better than one Crosshair™ Xtreme is two of them on a diversity system. &nbsp;The Crosshair™ XTreme Diversity System combines 2 Crosshair™ Xtreme antennas aimed upward and apart giving you wide beam of long range/high penetration coverage everywhere in front of you. &nbsp;Mounting directly to the Fatshark cooling fan intake is just under 3 minutes. &nbsp;Just screw down the mounting plate, connect the included cables to your diversity receiver and enjoy the benefits of a long range antenna system with full field coverage.</p><p><br></p><h4><b>SPECIFICATION</b></h4><p><br></p><ul><li><p>Gain: 10.25dbic</p></li></ul><ul><li><p>Axial ratio: 0.99 (measured)</p></li></ul><ul><li><p>Bandwidth: 5080Mhz-6000MHz</p></li></ul><ul><li><p>Flight beam: 120 degrees</p></li></ul><ul><li><p>Polarization: RHCP</p></li></ul><ul><li><p>-3db point: +/- 30 degrees</p></li></ul><p></p>
