4G SMA Antenna Wi-Fi GPS Combination Antenna Combo Antenna

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，Wi-Fi communication, meets the on-board T-BOX host equipment, has the characteristics of multi-system compatibility and high-precision measurement, and is widely used in mapping, ocean survey, geological deformation monitoring and other fields.

Key Features

• High performance amplifiers & filters

This combination antenna has built-in amplifiers and filters to enhance the received signal and reduce noise interferences.

• Anti-interference

To ensure stable operation in complex environments, this antenna is specially designed to reduce interference from other wireless devices.

• Multi-band Coverage

The antenna usually supports 4G&Wi-Fi network connection communication, while providing GNSS high-precision navigation functions.
