HELICAL 5.8 GHz 10 dBi LHCP Antenna — 7 Turns, Open, SMA

The HELICAL antenna from SkyReach is a high-quality circular antenna designed for stable wireless communication in the 5.6 - 5.9 GHz range. The model features an increased gain of up to 10 dBi, left-hand circular polarization (LHCP), and a 7-turn design, ensuring reliable signal reception and transmission over medium and long distances. The antenna has an open design and a standardized SMA connector, making it compatible with numerous radio devices and FPV systems.

Description and Advantages: This antenna is ideal for FPV video transmission systems, UAVs, ground stations, and other applications requiring circular polarization to reduce multipath noise. With a VSWR below 1.5, the antenna ensures minimal power loss at the input, and the 1 mm enameled copper conductor guarantees structural strength while maintaining the necessary electrical conductivity parameters.

Key Features

• Frequency Range: 5.6 - 5.9 GHz
• Gain: 10 dBi
• VSWR (Voltage Standing Wave Ratio): less than 1.5
• Antenna Conductor: 1 mm enameled copper wire
• Beamwidth: 39°
• Number of Turns: 7
• Polarization: LHCP (Left-Hand Circular Polarization)
• Type: Open-type Helical circular antenna
• Connector: SMA

The antenna's layout and geometry provide directional action with circular polarization, which enhances channel stability in conditions of reflections and interference. The design of the turns with enameled copper wire combines low weight and sufficient mechanical rigidity — important characteristics for mounting on drones and mobile platforms. The VSWR and gain parameters meet the requirements of many modern 5.8 GHz data transmission systems, making the antenna a versatile solution for SkyReach equipment and compatible devices.

Thanks to its open design and standard SMA connector, the antenna easily integrates into existing systems without complex adapters. The choice of left-hand polarization (LHCP) makes it compatible with other LHCP devices and helps avoid polarization conflicts in systems using different antenna types. Before installation, it is recommended to ensure connector compatibility and mechanical fastening for reliable contact and positioning stability.
