Product Description:

Ø Covers all frequency points of GPS L1/L2/L5, GLONASS L1/L2, BD2 B1/B2/B3, GALILEO E1/E2/E5/E6, and supports BDS-3 system.

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 Pre-filtering is used to effectively suppress out-of-band strong jamming signals, avoid amplifier saturation, and improve system reliability.

Ø Built-in lightning protection circuit effectively protects the amplifier and ensures normal operation in outdoor thunderstorm environments.

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

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

Ø IP67 meets the complex outdoor environment and can work normally outdoors for many years.
