4.9-6GHz. Every Band. Every Protocol. One Antenna.Most FPV antennas are tuned for a narrow slice of the 5.8GHz band. The Momoda2 4.9G-6G spans 4.9GHz to 6GHz—the full FPV spectrum from low-band long-range frequencies through standard 5.8GHz channels to 6GHz HD system bands. High parameter consistency across all frequency points means your signal stays stable whether you’re on 4.9G for long-range or 5.8G for racing. Compatible with both HD and analog VTX systems. One antenna covers your entire fleet.3.55dBi Peak Gain. 88% Radiation Efficiency.At 5150MHz, the Momoda2 achieves 3.55dBi gain with 88% radiation efficiency—converting nearly nine-tenths of your VTX power into airborne signal. Average gain across the band is 3.03dBi with 76.5% average efficiency. Compare that to budget antennas that waste 40-50% as heat. More of your milliwatts reach the sky. Less thermal stress on your VTX.SWR ≤1.28. Near-Perfect Impedance Matching.At the center of its tuned range, the Momoda2 4.9G-6G achieves SWR ≤1.28—approaching theoretical perfection. Average SWR across the full band is 1.57, still well within the ‘excellent’ range. Your VTX sees a near-ideal 50Ω load. Minimal power reflection. Maximum signal in the air. Premium low-loss SMA connector further reduces insertion loss for lower overall SWR and higher effective gain.RG141 Cable. Low Loss. High Flex.The Momoda2 uses thick RG141 coaxial cable—lower loss per meter than the thinnerr RG178 used in budget antennas. At 5.8GHz frequencies, cable losses accumulate fast. RG141 preserves more signal between the VTX and the radiating element. The result: better range at the same power setting.Omnidirectional Coverage. Stable Through Maneuvers.The omnidirectional RF design provides wide, uniform coverage that holds signal through aggressive banking, rolling, and high-speed turns. Unlike directional high-gain antennas that require constant aiming, the Momoda2 forgives acr0. Your signal stays stable even during extreme maneuvers.ABS Shell. RG141. SMA. Built to Last.The ABS enclosure is crash-resistant, corrosion-resistant, and highly sealed. The RG141 cable resists kinking and wear. The premium SMA connector minimizes transmission loss. Each antenna undergoes strict spectrum analyzer testing before shipping to verify VSWR stays within standard limits. You get the performance printed on the spec sheet.Two Lengths. Your Frame. Your Choice.– 90mm (11.2g): Compact and lightweight for racing frames and tight builds.- 170mm (17.6g): Extended reach for larger frames, better signal clearance, and long-range setups.LHCP or RHCP. Match Your Fleet.Available in both Left-Hand and Right-Hand Circular Polarization. Match your entire fleet to one polarization for maximum signal transfer. -25dB cross-polarization suppression aggressively rejects opposite-hand interference in multi-pilot environments.Key Features Bullet Points* 4.9-6GHZ ULTRA-WIDEBAND: Full FPV spectrum coverage.
