The antennas are 9dBi circular polarized helix antennas (half sphere helix). The circular pattern is the key to its success. With a linear antenna, for the best signal, or most information received by the receiver antenna, both antennas have to be of the same orientation. If they are everything is fine as long as you are in range. However, FPV having a moving antenna on the plane, this then means the antennas orientation will move depending on the planes position, its banking angle and its angle of attack.
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.
