share:
The Beidou handheld dual-model external antenna supports the reception of S and B3 frequency signals, and the transmission of L frequency signals. It has good resistance to vibration, impact, water, and salt fog corrosion. It is small in size and can be attached using a magnet, making it suitable for field work.
