Product Description:

Ø Full frequency measurement choke coils covering GPS L1/L2/l5, GLONASS L1/L2, BDS B1/B2/B3, GALILEO El/E5a/E5b/E6.

Ø The multi-feed point design and completely symmetrical antenna structure realize the coincidence of the phase center and the geometric center. The phase center is stable and the positioning accuracy is high.

Ø Multiple choke coil design to achieve excellent multi-path rejection effect.

Ø The antenna has a high cross-polarization ratio and strong resistance to multi-path jam.

Ø Pre-filtering is used to effectively suppress strong out-of-band jamming signals and improve system reliability.

Ø Equipped with a breather valve to ensure that the internal and external air pressure is balanced when the antenna is working.

Ø The radome is made of high-quality materials with good weather resistance and anti-aging, which is suitable for long-term work in outdoor environments.

Ø Overall waterproof design, the waterproof level of core components reaches IP67, which can meet the requirement of normal operation outdoors for many years.
