This external active GPS antenna gives a GPS breakout board a boost. It is made for modules that receive signals from GPS, BeiDou or GLONASS satellites, draws between 5 and 15 mA and adds 28 dB of gain. The 1.8 m cable makes it easy to reach wherever you need it.
A patch antenna with a preamplifier does the receiving, and an internal magnet lets you fix it to a metal surface, such as a car roof or a machine body, without tools.
The antenna works at 1575.42 MHz, has a noise factor below 1.5 dB and a VSWR below 2. The cable is RG174 and the connector is SMA. It operates from -40 to 85 C. The maker says it is easy to use and does not require RF or antenna knowledge.
Check that your GPS module can supply power to an active antenna through its antenna connector (often called bias voltage or antenna power), and that the connector on your module matches SMA or adapts to it. Place the antenna flat with a clear view of the sky, away from other transmitters.
Makers and installers who want to improve the reception of a GPS module inside a vehicle, enclosure or building.
Place the antenna flat on a metal surface with the cable pointing away from other electronics, and avoid tight bends in the RG174 cable. Inside a vehicle, the dashboard works but a roof mount is better for reception. If the antenna needs bias power, check the module's documentation and never connect it to a supply that exceeds the voltage the module provides.
