Product Description:

Ø The BT/WIFI input port is equipped with a filter to avoid crosstalk within the device.

Ø The unique design of BT/WIFI&4G has higher antenna gain and can realize long-distance data transmission.

Ø The antenna part adopts a multi-feed point design, which has a higher precision phase value and reduces the impact of the antenna on survey errors.

Ø The low-noise amplifier part adopts a pre-filtering scheme, which filters the received signal first and then amplifies it, which can effectively reject 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 harsh outdoor environments.

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