This antenna combines GPS and GLONASS signals for high positioning accuracy in space-restricted environments. It has a 3 m cable, a flat magnetic surface, an IP67 waterproof rating, UV resistance and a SAW filter that protects against RF interference. It suits Raspberry Pi HATs and Arduino shields, and the maker says you do not need RF expertise to use it.
A patch antenna with a preamplifier does the receiving, and an internal magnet allows fixing to a metallic surface.
The operating frequency is 1575.42 MHz, LNA gain is 27 dB without the cable and the noise figure is 1.5 dB. It runs on 3 to 7 V DC and draws about 15 mA. The connector is SMA male, the impedance is 50 ohm, the cable is 3 m and the weight is 60 g.
Because it is an active antenna, make sure your module supplies power to the antenna through its connector or that you add a bias tee. Mount it on a flat metal surface such as a roof, or in a window, with a clear view of the sky, and run the cable so that it is not pinched.
Makers who need to move a GPS receiver's antenna outdoors, for example on a vehicle, a weather station or a tracker enclosure.
Use the magnetic base on a steel surface for a firm hold, or fix the antenna with the adhesive method on other surfaces. Run the cable so that water drips away from the connector, seal the SMA joint with self-amalgamating tape if it will be outdoors and keep the cable away from power wiring. Test the fix before you permanently secure the antenna.
