HELICAL 5.0GHz Antenna — A Reliable Solution for Circular Polarization

Introducing the Helical antenna from SkyReach — a model that combines the compactness of an open-type design with high efficiency in the 4000-5900 MHz range. Product name: HELICAL 5.0GHz 16dBi RHCP Antenna, 9-turn, Open Type SMA. Designed for applications with right-hand circular polarization (RHCP) where stable and directional coverage is required.

This antenna demonstrates excellent VSWR performance: in the 4000-5900 MHz range, the antenna consistently has a VSWR below 1.5, ensuring minimal losses. Separately, the technical specifications provide a VSWR value of 1.2 for 4000-5300 MHz. Such performance makes it one of the best in its class for impedance matching stability.

The antenna has a beamwidth of 30 degrees, providing focused coverage for signal transmission and reception over medium and long distances. The design includes 9 turns (turns: 9) with a 1 mm enameled copper wire conductor, ensuring an optimal balance between mechanical strength and electrical characteristics.

Design Features: The open-type Helical antenna ensures easy installation and cooling, while its compact size (reflector diameter 54 mm) and short cable (about 9 cm) facilitate integration into various systems. Thanks to right-hand circular polarization (RHCP), the antenna better resists multipath interference and reduces mutual interference with linearly polarized devices.

Application: The antenna is suitable for unmanned systems, radio relay links, industrial and professional wireless solutions in the 4–5.9 GHz range, where matching stability and directivity are critical.
