CAR T-BOX ANTENNA

4G LTE/GNSS Antenna

Product Overview

The combined vehicle antenna adopts multi-feed points and a completely symmetrical structure, which reduces the error of the antenna when measuring.

The antenna has the characteristics of high gain, directional beamwidth, low elevation signal reception, etc., to ensure that the satellite signal can be received

Usually in a severely closed environment. In the low noise amplification part, the pre-filtering scheme is adopted to effectively suppress out-of-band

interference and improve system reliability.
