Product Description:
Full frequency measurement choke coils covering GPS L1/L2/I5, GLONASS L1/L2, BDS B1/B2/B3, GALILEO El/E5a/E5b/E6.
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.
Multiple choke coil design to achieve excellent multi-path rejection effect.
The antenna has a high cross-polarization ratio and strong resistance to multi-path jam.
Pre-filtering is used to effectively suppress strong out-of-band jamming signals and improve system reliability.
Equipped with a breather valve to ensure that the internal and external air pressure is balanced when the antenna is working.
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.
Overall waterproof design, the waterproof level of core components reaches IP67, which can meet the requirement of normal operation outdoors for many years.
