The GEPRC Momoda2 5.8G Dual Antenna is a compact, high-efficiency 5.8GHz FPV antenna built on a dual-core RF solution — combining FPC and PCB structures to improve signal frequency consistency while minimising transmission power loss. Available here in the RHCP SMA 90mm configuration, it’s a direct performance upgrade over standard rubber duck antennas for analog FPV builds.
Why choose the Momoda2 Dual Antenna?
The Momoda2’s dual-core RF architecture gives it a measurable advantage over single-element stub antennas — improved directional compatibility means stronger signal across a wider range of flight angles, not just when the drone is directly overhead. Combined with an ultra-low VSWR of ≤1.43 and 85% radiation efficiency, it transfers more of your VTX’s power into usable signal and less into heat. Pair it with components from our FPV VTX collection for a complete video system.
Key features
Dual-core RF technology
A dual-core FPC+PCB structure enhances gain and expands omnidirectional coverage compared to single-element designs — particularly improving directional compatibility during aggressive FPV manoeuvres.
Ultra-low VSWR ≤1.43
A VSWR of ≤1.43 ensures highly efficient power transfer from your VTX to the antenna, minimising reflected power and reducing signal loss — particularly important at higher VTX power levels.
3.8dBi gain with 85% radiation efficiency
3.8dBi gain across the full 5.3-6GHz band, with 85% radiation efficiency and -25dB cross-polarisation suppression — clean, consistent signal with minimal interference from adjacent channels or reflections.
RHCP polarisation
Right-hand circular polarisation matches the majority of 5.8GHz FPV VTX antennas and goggle receivers, reducing multipath interference and maintaining signal consistency through dynamic flight orientations.
Spectrum analyser tested
Every Momoda2 unit is individually tested with a spectrum analyser before leaving the factory to verify VSWR compliance — not just batch-tested, but unit-by-unit quality control.
Ultrasonic welded assembly
Ultrasonic welding provides a tight, secure internal assembly with no adhesive failure risk — more durable than glued constructions during vibration and crash impacts.

Build compatibility
SMA connector — compatible with the majority of 5.8GHz FPV VTX units and goggle receivers using standard SMA ports. The 90mm cable length suits most quad builds with internal stack routing. Check your VTX connector type before ordering — units with MMCX will require a separate adapter. Browse our full VTX range for compatible transmitters.
