This is a GPS active antenna designed specifically for GPS applications. It has signal amplifiers built into the unit, and its ceramic patch design gives excellent stability and sensitivity thanks to high-performance ceramic material. It is suitable as an aerial for drones and for GPS module receivers and tracking projects.
The antenna connects with a U.FL (female) connector, often called IPEX, which is the small connector used on many modern GPS boards.
The model is LWC-GPS-CHIP-28, with a 50 ohm impedance, RHCP (right-hand circular) polarisation, a VSWR below 1.5 and a gain of more than 28 with the built-in LNA. The housing is tin plated. The frequency range is quoted for the GPS L1 band around 1575 MHz, although the range line is printed with wrong units.
For best performance, mount the antenna flat with a clear view of the sky, away from carbon fibre plates, video transmitters and power wires. Keep the cable short and avoid sharp bends in the fine coaxial lead.
Drone builders, tracker makers and hobbyists who need to add or replace an active GPS antenna with a U.FL connector.
Route the fine coaxial lead so it is not pinched by covers or frame parts, and avoid tight kinks near the U.FL connector, which is delicate. Press the connector on squarely until it clicks and do not repeatedly plug and unplug it. If you can, fix the antenna with a small piece of double-sided foam tape to keep it flat against a non-metal surface.
