The LHCP Airblade is a left hand circularly polarized antenna replacement for your whip antennas.  These will greatly increase your video range and clarity.  Upgrade to a long range system by adding a 7.5dbic or 9.5dbic helical or crosshair antenna for your receiver.

Contains TWO antennas, one RX and one TX antenna

Antenna size (not including SMA connector) roughly 70mm diameter and 30mm tall.  Connector is about 20mm high.

This amazing creation is built by Alex Greve (IBCrazy).  These 2.4GHz antennas are left hand circular polarized, and can be used with linearly polarized antennas (with some loss) or a more perfect match is another left hand circularly polarized antenna.  Not to be used with right hand circular polarized antennas.
