HELICAL 5.8GHz 18 dBi RHCP Antenna, 27-Turn, Open-Type SMA — Overview

HELICA Antenna from SkyReach is a specialized solution for tasks requiring reliability, high directivity, and signal stability. The model is positioned as an open-type antenna with an SMA connector, making it compatible with a wide range of radio equipment, particularly for the 5.8GHz band. Its design provides high gain of 18 dBi and right-hand circular polarization (RHCP), which reduces losses from reflections and improves reception in challenging conditions.

Key Characteristics and Parameters

• Frequency Range: 4.750-6.000 MHz (covers 5.8 GHz)
• Gain: 18 dBi
• Beamwidth: 20°
• Number of Turns: 27
• Polarization: RHCP (Right-Hand Circular Polarization)
• VSWR: 1.5
• Conductor Material: 1 mm enameled copper wire
• Type: Open helical antenna with SMA connection

Advantages of Use

The HELICA antenna offers several advantages that make it an excellent choice for professional and military communication systems: high directivity with a 20° beamwidth ensures precise signal transmission over long distances; 18 dBi gain guarantees quality performance even in noisy environments; RHCP circular polarization minimizes the impact of multipath signals; low VSWR (1.5) means efficient power transmission with minimal losses; the 1 mm enameled copper conductor enhances the antenna's mechanical strength and durability.

Areas of Application

• Tactical and field communication systems requiring stability and reliability.
• Radio relay links for long-distance data transmission.
• Monitoring and reconnaissance systems in field conditions.
• Installations on UAVs and drones to ensure a stable communication channel in challenging conditions.

This model is ideal for professionals who require an open antenna design with a standard SMA connector and wide frequency coverage. Thanks to the combination of 27 helical turns, 18 dBi gain, and RHCP polarization, the antenna demonstrates excellent results in transmission under difficult conditions, ensuring minimal losses and stable communication.
