Shipborne Beidou dual-mode antenna



Product Description:

1, receiving antenna low elevation gain, low noise factor, to ensure stable positioning, communication functions;

2, open the power amplifier does not affect the reception of S and B3, the output power is stable and reliable;

3, built-in metal cavity filter, improve transmit-receive isolation and reduce emission spurious;

4, the antenna shell is fully sealed, meet the requirements of IP67, can work in the outdoor harsh environment for a long time;

5, the antenna has anti-ultraviolet, anti-sun exposure, anti-temperature changes, etc., suitable for complex Marine environment.
