Starting from the price-performance ratio, is often used as a Repeater grid parabolic antenna donor antenna. Due to the parabolic good focus, parabolic antenna set shooting ability, grid parabolic antenna 1.5 m in diameter, in the 900 band, which can be g = gain 20dBi. It is particularly suitable for point-to-point communication, for example it is often used as the donor antenna Repeater.
Parabolic grid-like structure, in order to reduce the weight of the antenna, and second, in order to reduce wind resistance.
