Directional antenna with very high gain 21dBi designed for frequencies 5.18-5.8GHz. The antenna is especially suitable for long distance flights. Due to the antenna's larger size and narrow radiation pattern, it is suitable when installed on a tripod or antenna tracker. The antenna connects via a flexible coaxial cable with a length of 38cm terminated with a SMA/RP-SMA connector. The antenna has linear vertical polarization.
