Product Usage:
This antenna meets the current needs of multi-system compatibility of survey equipment and extremely high-precision micro-deformation survey. It is mainly used in some occasions that have extremely high requirements on survey accuracy, such as earthquake prediction, high-precision differential base stations and other application environments with demanding conditions.

Based on the final image provided, here is the transcribed product description: Product Description: Multiple choke coil design achieves excellent multi-path rejection effect and high phase center stability. 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. Built-in voltage stabilizing circuit can operate normally within a wide input voltage range. Built-in ESD design provides guarantee for product safety. LNA gain is high and the cable length can reach 100m. 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.
