The 1.3GHz BluBeam Ultra Airscrew (Cloverleaf) antenna is a high quality circularly polarized transmitter antenna. Use this type on your video transmitter.

This amazing creation is built by Alex Greve (IBCrazy).  The cloverleaf antenna design has proven to be one of the best antenna designs for FPV flying, and this Airscrew improves on that design by integrating a balun to prevent interactions with extension cables or some other part of the RF system.  This 1.3GHz antenna is right hand circular polarized, and can be used with linearly polarized antennas (with some loss) or a more perfect match is another right hand circularly polarized antenna.  Not to be used with left hand circular polarized antennas.

Includes RHCP cloverleaf antenna mounted to a 2″ (5cm) cable with integrated balun. Has a straight SMA male plug.
