Description:

Consult

Product Description:

Ø Covering three systems and three frequency points of GPS L1, BDS B1, and GLONASS L1.

Ø It has the advantages of low noise, low current, high gain, high reliability, and anti-jamming.

Ø It complies with the national promulgation of GB50057-2000 "Lightning Protection Code for Building Design". It can effectively protect the timing module and amplifier and is not easily damaged when working in harsh outdoor environments.

Ø The installation clamp is made of 316 stainless steel and passivated.

Ø The metal bottom shell is powder-coated and the radome is made of high-quality materials with good weather resistance and anti-aging, suitable for long-term work in outdoor environments.

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