BT-T319B RDSS antenna is an external antenna used for receiving s-frequency satellite signals and transmitting Beidou L-band signals. The antenna unit adopts an integrated design to miniaturize the antenna while maintaining high gain and wide pattern beam. has good high and low elevation performance. It is widely used in shipboard, shipboard, vehicle, handheld devices and other fields. The antenna part adopts a symmetrical design to reduce the impact of the antenna on the accuracy error and the phase center is stable; The antenna unit adopts double-feed technology. The antenna unit has high gain, wide directional pattern beam, and good signal reception at low elevation angles. The multi-feed structure gives the antenna good circular polarization axial ratio characteristics. The bottom is magnetic for easy outdoor installation. Due to different batches, there may be differences in product appearance, color, and printed text, which will not affect the use.
