Helical RHCP Antenna 17.8 dBi 22 Turns 4.9-6.1 GHz from

The Helical Antenna is a spiral circular antenna from the manufacturer, designed for stable signal transmission and reception in the 4.9-6.1 GHz range. Its 22-turn design ensures high directivity and reliable operation over long distances, while right-hand circular polarization (RHCP) minimizes losses when interacting with other polarizations. This device combines compact size with efficiency: 17.8 dBi gain significantly increases communication range and quality.

• High gain: 17.8 dBi for extended coverage and improved communication reliability.
• Optimal spiral architecture: 22 turns ensure a stable radiation pattern.
• Right-hand circular polarization: RHCP for compatibility with modern radio systems and reduced interference.
• Connector: SMA — a standard solution for quick connection to various equipment.
• Plastic casing — lightweight and resistant to environmental factors, suitable for field conditions.
• Compact dimensions: 70*52*293 mm and low weight 81 g for easy installation and transport.

Technical Specifications

The Helical antenna from is designed for various applications: drone video transmission, terrestrial radio links, amateur and professional radio systems, satellite equipment, and industrial wireless networks. The combination of a wide operating range of 4.9-6.1 GHz and RHCP makes it compatible with many modern solutions requiring stable video, data, and command transmission.

Thanks to its low weight of 81 g and compact dimensions of 70*52*293 mm, the antenna easily integrates into UAV kits or stationary communication nodes without significantly increasing the load. The plastic casing material provides protection against atmospheric factors during outdoor operation.

The SMA connector ensures simple and quick connection to transmitters and receivers. The 17.8 dBi gain combined with a beam pattern of ~35-40° creates an optimal balance between directivity and coverage width, which is important for video transmission from mobile platforms and for stable terrestrial links.
