Product Description

Helical Antenna RHCP 16.3 dBi 18 Turns 4.9-6.1 GHz (30 cm) from the manufacturer is a high-quality helical antenna with right-hand circular polarization (RHCP), designed for reliable signal reception and transmission in the 4.9-6.1 GHz range. Its design ensures stable communication even when the receiver rotates or the antenna's orientation changes, making it an excellent choice for FPV systems, drones, ground receivers, and stationary wireless solutions. The casing is compact and lightweight: dimensions 70*52*240 mm, cable length 300 mm, total length about 30 cm, weight only 67 g.

Key Advantages

• High gain 16.3 dBi — provides increased range and improved coverage.
• Right-hand circular polarization (RHCP) — minimizes losses when the reception angle changes and enhances channel stability.
• Optimized beam angle 40-45° — a balance between range and coverage width for stable reception at medium and long distances.
• Reliable SMA connector — easy connection to compatible equipment and quick antenna replacement if needed.
• Lightweight plastic casing — weighs only 67 g, which is crucial for mounting on light drones and mobile platforms.

Applications

The Helical antenna is designed for a wide range of applications: FPV flights, long-range radio communication, satellite, and specialized communication systems where polarization stability and high gain are required. It is suitable for mounting on light drones, stationary base stations, and portable receivers, where weight and size optimization and reliable SMA connection are important.

Technical Specifications

The antenna is presented in the category: Antennas > Circular Antennas > Helical Antenna. The manufacturer guarantees the quality of components and stability of characteristics within the typical operating frequency range. Thanks to its design and features, this model is ideal for use in professional and amateur solutions where connection reliability, compactness, and minimal weight are important.

Why choose this model: the combination of high gain 16.3 dBi, 18 turns for better directivity, and RHCP polarization makes the antenna resistant to many interferences and unfavorable reception conditions. Compact dimensions of 70*52*240 mm and a weight of 67 g allow it to be installed on quadcopters and light platforms without significantly affecting flight characteristics or equipment ergonomics.

Purchase and compatibility: the antenna comes with an SMA connector, compatible with most controllers, transmitters, and receivers on the market. The additional cable length of 300 mm ensures convenient installation and connection in confined spaces.
