Introducing the HELICAL 5.8GHz 16dBi LHCP (Left-Hand Circular Polarization), 17-turn, enclosed-type antenna with SMA connector from SkyReach. This model combines a helical design with circular polarization and is intended for FPV flights, remote sensing, and applications where signal quality and penetration are critical. The description also mentions a modification called Penetrator V2, which demonstrates improved performance in real-world conditions.

The antenna operates effectively in the 4800-5900 MHz range and consistently maintains a VSWR below 1.3 within this range, making it one of the best in its class. At the same time, the technical specifications indicate a VSWR below 1.2 (typical value), which highlights the antenna's high matching with transmission paths. With a gain of 16 dBi and a focused beamwidth of approximately 30 degrees, expect a significant increase in range and improved signal penetration. For the most extreme flights and optimal reception, it is recommended to combine the antenna with an antenna tracker.

Description and Features

This enclosed helical antenna features a compact reflector with a diameter of 55 mm and a construction made of enameled copper wire with a diameter of 1 mm. The main configuration is 17 turns, as specified in the characteristics; some materials also mention an 18-turn variant as a modification for specific applications. Connector: SMA. Polarization type: LHCP (Left-Hand Circular Polarization). The maximum input power of the antenna is 50 W. The antenna weighs approximately ~100 g, and the package includes 1 piece.
