Generic 25x25x8mm 28dB GPS Antenna 5cm for NEO-6M NEO-7M NEO-8M

This 25x25x8mm active ceramic patch antenna is designed as a direct replacement or external signal upgrade for UAV navigation units and flight controllers using u-blox NEO-6M, NEO-7M, or NEO-8M GPS modules. Integrating an active low-noise amplifier with 28 dB of gain, it improves satellite signal reception and reduces time-to-first-fix on multirotor, fixed-wing, and autonomous survey builds.

Key features

• Integrated 28 dB active low-noise amplifier boosts weak GPS L1 signals for faster satellite acquisition and dependable positional lock.

• Right-hand circular polarisation mitigates multipath interference and signal degradation caused by carbon fibre frames and ground reflections.

• Standard 50 mm micro-coaxial lead terminating in a U.FL connector enables direct plug-in connectivity without soldering.

• Compact 25x25x8 mm ceramic dielectric element fits cleanly inside standard drone GPS mast pucks and custom 3D-printed canopies.

• Active bias-T design draws operating power (3.0 V to 5.0 V DC) directly across the coaxial feedline from the host receiver board.

Before purchasing, confirm that your target GPS module carries a compatible female U.FL receptacle and outputs 3.0 V to 5.0 V DC bias voltage along the RF signal trace to power the internal amplifier. When installing inside a GPS puck or canopy, face the ceramic patch directly towards the sky and maintain maximum physical clearance from switching ESCs, video transmitters, telemetry radios, and high-current power wiring to prevent RF desensitisation.
