Helical Antenna RHCP 12 dBi 10 Turns 4.9-6.1 GHz (30 cm)

Brand:. The Helical Antenna (helical helix antenna) from — is a compact and highly efficient radio element designed for reliable signal reception and transmission in the 4.9-6.1 GHz range. Its 10-turn spiral design provides right-hand circular polarization (RHCP), which significantly reduces signal loss from reflections and antenna orientation errors, enhancing communication channel stability.

The antenna gain is 12 dBi, and the beam angle is approximately 45-50°, providing balanced directivity with sufficient coverage without excessive pattern rigidity. This combination of parameters makes the model ideal for applications in FPV systems, access points, radio communications, and satellite or mobile solutions where the quality of directional coverage and stable polarization are crucial.

Technical Specifications and Design

The housing material is plastic, ensuring low weight and increased corrosion resistance for outdoor or mobile use. Its compact dimensions make the antenna convenient for mounting on drones and lightweight structures: size 70*52*135 mm, and total weight is only 46 g. The kit includes a 300 mm (30 cm) cable with an SMA connector for quick and easy connection to equipment.

The antenna is designed for applications requiring reliable transmission over medium to long distances with minimal interference. Thanks to its RHCP right-hand circular polarization, it reduces the impact of multipath and reflected signals, making the channel more stable when the receiver's orientation changes or in conditions of reflections from surfaces. The spiral shape and 10 turns ensure a stable radiation pattern and high effective gain of 12 dBi.

The model is convenient for engineers, installers, and enthusiasts looking for a compact, lightweight, yet powerful antenna for use in FPV systems, access points, and private and professional radio communication systems. The simple SMA connector and 30 cm cable make integration with equipment quick and convenient.
