4G LTE/WIFI/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.
- The combined vehicle antenna covers GPS L1, BDS second-generation B1/, GLONASS L1, 4G，WIFI communication, meets the on-board T-BOX host equipment,
