Product Description:

Ø High gain, wide beam, and good signal reception at low elevation angles, ensuring normal star collection in some severely obscured situations.

Ø The filtering part adopts a pre-filtering scheme, which filters the received signal first and then amplifies it, which can effectively suppress out-of-band strong jamming signals, avoid amplifier saturation, and improve the reliability of the system.

Ø The low-noise amplifier part uses a low-current, high-linear chip, which meets both low noise and wide dynamic range, and can effectively amplify weak satellite signals.

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

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