HELICAL Antenna 5.8GHz 16dBi RHCP, 17-turn, Enclosed Type SMA — SkyReach

Introducing the helical antenna from SkyReach — a versatile solution for long-range FPV flights and challenging communication conditions. In the general description, the manufacturer emphasizes the possibility of custom manufacturing to meet your needs. In the 4800-5900 MHz range, the antenna demonstrates excellent performance: VSWR consistently below 1.3, making it one of the best in its class, with technical specifications also indicating a typical VSWR value below 1.2. The antenna has a powerful 16 dBi gain, which significantly increases range and communication quality.

The helical design provides circular polarization (RHCP), which reduces losses due to mutual polarization tilt between the receiver and transmitter. The promotional description mentions the FPV model — Penetrator V2 with an impressive design and 18 turns, while the listed specifications state 17 turns — both values are provided in the original description. For maximum effectiveness, it is recommended to combine the antenna with an antenna tracker, especially for extreme long-range flights.

Advantages and Purpose

The antenna is ideal for long-range FPV sensing, where focused coverage and signal penetration are required. The enclosed design ensures stable operation in field conditions and protects the antenna elements. The beamwidth of approximately 30 degrees at medium distance provides concentrated gain; at close distances, the beam can expand to approximately 60 degrees.

Specifications:

• Bandwidth: 4800-5900 MHz
• Beamwidth: 30 degrees for maximum gain, expands to approximately 60 degrees at close distances
• Gain: 16 dBi
• Reflector diameter: 55 mm
• Cable length: approximately 9 cm
• Antenna conductor: 1 mm enameled copper wire
• Turns: 17 (18 turns are also mentioned in the description)
• Polarization: RHCP
• VSWR: below 1.2 (VSWR below 1.3 is mentioned in the 4800-5900 MHz range)
• Maximum input power: 50 W
• Connector: SMA
• Antenna weight: approximately 100 g
• Quantity included: 1 piece

This antenna is suitable for integration with ground trackers, long-range transmitters, and FPV systems where signal stability and penetration are critical. Please check the compatibility of the SMA connector with your equipment or use an adapter if necessary. The weight of about 100 g and compact dimensions make installation simple, and the ~9 cm cable length ensures convenient connection without unnecessary strain.
