the 2 2.4ghz helix antennas for rc control are 10.5dBi and have a 55 degrees beam width
It comes with 3 u.fl cables to rp-sma female and and a plastic mount that clips onto the metal handle of the radio.
With circular polarization, no matter what axis the transmitters antenna is placed at, the circular pattern still matches the receiver so no losses are incurred at all. This gives you much more penetration through trees, behind obstacles and more.
