2.4GHz Spiral Directional FPV Antenna 13dBi Gain Circular Polarized RPSMA Long Range (Option 3)

Gain 2.4 GHz Spiral Directional Antenna Option 3 (Internal thread, lefthand) A compact directional spiral antenna designed for reliable longrange FPV and remote control links. The spiral element produces circular polarization and a focused radiation pattern to improve video stability and reduce interference from offaxis signals. Lightweight and easy to mount, this antenna is suited for racing, aerial photography, and other longdistance RC applications. Key benefits Stable longrange video and control: 13 dBi gain and a narrow 60 degrees radiation angle concentrate signal power toward the target direction to extend usable range and improve feed stability. Better signal quality: Spiral geometry delivers an improved axial ratio and circular polarization to reduce multipath loss and preserve image quality over distance. Simple installation and compatibility: RPSMAJ connector with internal thread lefthand option makes it compatible with many FPV transmitters and receivers while remaining easy to fit and align. Lightweight and compact: At 78 g and 100 x 100 x 50 mm size, it adds minimal weight to drones or ground stations. Features Frequency bandwidth: 2.3 GHz to 2.65 GHz, optimized for 2.4 GHz FPV systems. Polarization: Circular polarization for more reliable video links in realworld environments. Gain: 13 dBi for focused, longrange transmission. Radiation angle: 60 degrees to concentrate the signal and reduce offaxis interference. Impedance: 50 ohm for standard RF matching. Standing wave ratio: less than 1.2 across 2.4 GHz to 2.5 GHz band. Maximum power handling: 50 W. Connector: RPSMAJ with internal thread lefthand mounting (Option 3). Material: ABS housing, color black. Weight and size: 78 g, 100 x 100 x 50 mm. Practical use scenarios FPV racing: Mount on a ground receiver or chase vehicle to keep a stable, lowinterference video link during speed laps. Aerial photography and surveying: Use on a longrange ground station to maintain a steady video feed while capturing photos and video across larger areas. Longrange RC flights: Improve control link reliability for gliders and fixedwing models where maintaining a focused signal towards the aircraft reduces dropouts.
