Helical RHCP 14 dBi 12-Turn Antenna (4.9-6.1 GHz)

The Helical antenna (spiral antenna) from the manufacturer is a high-performance radio element designed for stable signal reception and transmission in the 4.9-6.1 GHz range. Right-hand circular polarization (RHCP) ensures minimal losses due to polarization mismatches, making this model ideal for FPV systems, satellite links, and long-range radio links.

The model has a nominal gain of 14 dBi, allowing it to concentrate energy in a narrow beam with a beam angle of approximately 45-50°. The spiral design with 12 turns provides high directivity and signal stability in multi-path reflection environments. The antenna is equipped with a standard SMA connector, ensuring easy integration with various transmitters, receivers, and video transmitters for drones and professional radio communications.

Advantages

The helical shape and construction materials provide the following advantages:

• high gain of 14 dBi for increased communication range;
• stable right-hand circular polarization (RHCP) to reduce interference and losses;
• compact and lightweight dimensions, important for mobile and light constructions;
• plastic casing that protects against weather influences and mechanical damage;
• compatibility with equipment thanks to the SMA connector.

Application

The Helical antenna is suitable for a wide range of tasks: FPV projects, satellite and terrestrial communication links, professional radio systems, long-range radio links, and other wireless communications where high reception quality and signal stability are important. Its light weight (only 54 g) and 300 mm cable length simplify installation in various configurations.
