HELICAL 5.8GHz 12dBi RHCP Antenna, 12-Turn, Open Type SMA

The HELICAL 5.8G 12dBi Antenna from SkyReach is a professional solution for FPV systems, combining high gain, directionality, and reliable right-hand circular polarization (RHCP). This open-type module is designed for transmitting and receiving video signals in the 4700-6000 MHz (5.8 GHz) range, ensuring stable long-distance communication and improved image quality during quadcopter or other UAV flights.

Key Features

The antenna has 12 turns, allowing it to achieve a high gain of 12 dBi and providing narrow, focused coverage with a beamwidth of approximately 30°. The use of RHCP polarization minimizes interference from other antennas and enhances connection stability. The antenna connector is SMA, making it compatible with a wide range of FPV transmitters and receivers.

Full Technical Specifications

The unique combination of parameters makes this antenna ideal for tasks where range, signal stability, and interference minimization are crucial: FPV video systems, control and surveillance missions, fast real-time video streaming, and other drone applications. Thanks to its low VSWR (≈1.5) and high permissible power (up to 50 W), the antenna efficiently transmits energy without significant losses or overheating.

Advantages of Use

• Wide frequency range 4700–6000 MHz, optimal for modern FPV solutions.
• High gain 12 dBi for stable reception/transmission over long distances.
• Right-Hand Circular Polarization (RHCP) reduces the impact of cross-polarization and interference.
• Focused coverage (beamwidth ~30°) allows concentrating energy in the desired direction, reducing side noise.
• Robust construction with 1 mm enameled copper wire and a 54 mm diameter reflector.
• Compact weight ≈52 g and short cable ≈9 cm ensure easy mounting on a drone.

The antenna is available in an open type with an SMA connector, allowing for quick replacement or installation on various transmitters. It is designed for both FPV enthusiasts and professionals who require a reliable video transmission channel without delays or interference. Custom antenna manufacturing is also available — technical parameters can be adapted to your needs.
