Momoda2 5.8GHz DUAL FPV Antenna with Dual-Core RF, 3.8dBi Gain (+30%), SWR

Type: LHCP
Camera Resolution: Without
RC Drone Spare Parts: FPV Antenna
Frequency: 5.8GHz
Interface Type: SMA
Two radiating elements. 3.8dBi gain-30% more than single-core. 85% radiation efficiency. Ultrasonic welded. The Momoda2 DUAL maintains signal coverage through aggressive banks and turns-when single-element antennas develop weak spots.
Dual-Core RF. 30% More Gain. Zero Blind Spots.
Single-core antennas have one radiating element. When your aircraft banks hard or changes orientation relative to your ground station, signal strength dips as the radiation pattern develops nulls. The Momoda2 DUAL solves this with dual-core RF technology-two independent radiating elements in a stacked configuration. Field testing confirms a 30% gain improvement (3.8dBi vs. 2.45dBi) over the single-core Momoda2. More importantly, the dual-core architecture provides superior directional compatibility-maintaining signal coverage through aggressive banking, turning, and high-maneuver situations.
SWR 1.43. 85% Radiation Efficiency.
SWR 1.43 across the 5.3-6GHz band. 85% average radiation efficiency. Near-perfect impedance matching converts the vast majority of VTX power into airborne signal-not heat reflected back into the board. Less thermal stress. More range from the same power setting.
RHCP Circular Polarization. -25dB Cross-Polar Rejection.
Right-Hand or Left-Hand Circular Polarization naturally suppresses multipath interference. -25dB cross-polarization suppression aggressively rejects opposite-polarization signals-clean feed in crowded multi-pilot environments.
FPC+PCB Construction. Spectrum Analyzer Tested.
Precision-etched flexible printed circuits bonded to rigid PCBs. Every radiating element is geometrically identical-no unit-to-unit performance variance. Each antenna undergoes individual spectrum analyzer testing to verify VSWR compliance before shipping.
Ultrasonic Welding. ABS Housing. One Solid Structure.
The ABS enclosure is ultrasonically welded into a single fused piece-no glue to degrade, no screws to loosen, no seams to separate in a crash. Premium antenna interface ensures secure, low-loss connection.
170mm + 57mm. 16.6g. Standard SMA.
Extended length design for larger frames, better signal clearance, and long-range applications. Standard SMA connector. 16.6 grams.
