Product Description:

Ø Multiple choke coil design achieves excellent multi-path rejection effect and high phase center stability.

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 Built-in voltage stabilizing circuit can operate normally within a wide input voltage range.

Ø Built-in ESD design provides guarantee for product safety. 

Ø LNA gain is high and the cable length can reach 100m.

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.
