Product Description:

Ø This antenna is a four-frequency survey satellite navigation antenna covering GPS L1/L2 and BDS B1/B3.

Ø Multi-feed point design realizes the coincidence of phase center and geometric center. The phase center is stable and the positioning accuracy is high.

Ø It has strong anti-burn function, and the maximum input power without damage is more than 2W.

Ø Built-in power devider, the received signal is divided into two channels and transmitted to different onboard equipment. The two ports can supply power to the amplifier internally at the same time or separately.

Ø Equipped with short circuit protection function and can also work normally within a wide input voltage range.

Ø Conforming design with the carrier to meet aerodynamic requirements.

Ø Circuit three-proof treatment.
