The Maple 5.8G-17dB antenna is a high-gain directional antenna that is vertically polarized when the antenna is used parallel to the ground. The corresponding transmitting rod antenna also needs to be used vertically on the ground. After the increase of antenna gain, the horizontal azimuth Angle of the antenna is relatively narrow, about 16°, which has high requirements for users and is more suitable for long-distance or supporting closed-loop AAT work.
