Product: 2pcs 5.8GHz Circular Polarized Mushroom Antenna Overview This 2 piece set of 5.8 GHz circular polarized mushroom antennas is designed for remote control aircraft applications. The omni directional design and circular polarization help maintain steady video and control signal reception, and the antennas are tuned with a standing wave ratio lower than 1.5 for efficient transmission and reception. Key benefits Improved range and angle: Omni directional pattern and optimized tuning help expand launch distance and reception angle for aerial setups. Stable signal for aerial photography: Circular polarization helps reduce multipath interference, making it a suitable match for aerial photography and FPV video links. Compact and lightweight: Mini size and composite material construction keep added weight and bulk to a minimum, preserving aircraft performance. Ready to install: Assembled class design simplifies replacement or upgrade of receiver antennas. Specifications Frequency: 5.8 GHz Polarization: Circular Gain: 2.0 dBi to 2.5 dBi Standingwave ratio: lower than 1.5 Quantity: 2 pieces per lot Connector: RPSMA Color: L RPSMA Material: Composite material Size: mini size Assembly: Assembled class Compatibility and use Designed for remote control receivers on helicopters and airplanes, suitable for vehicles and remote control systems. Classified under RC parts and accessories as antennas and upgrade parts and accessories as framerelated components. Compatible with standard RPSMA receiver connectors used in many FPV and RC setups. Practical scenarios Aerial photography: factory receiver antennas on a cameraequipped RC helicopter to help maintain a cleaner video feed during long or angle flights. Long range FPV flight: Install as receiver antennas on an airplane to extend reliable reception and reduce dropouts caused by signal reflections. Field replacement and upgrades: Carry as spare receiver antennas for quick onsite replacement during hobby flying sessions or events.
