The 11dBi circularly polarized antenna is a High-gain circularly polarized directional antenna. It is suitable for cruising through scenes, such as low-altitude crossing and long-distance flying. In actual use, adjust the inclination angle of the panel antenna appropriately. In the state of flying with the head down, the antenna is perpendicular to the ground; The transmitting antenna is right-handed circular polarization, which has the best effect.
