Helical RHCP 10 dBi 6-Turn 4.9-6.1 GHz Antenna — Overview

The Helical Antenna (spiral antenna) from the manufacturer — is a high-performance and compact transceiver designed for stable radio communication in the 4.9-6.1 GHz range. The model features right-hand circular polarization (RHCP), which ensures reliable communication when equipment orientation changes and minimizes the impact of reflected signals. Thanks to its spiral design, the antenna effectively transmits and receives signals over long distances even with a weak signal level.

Advantages and Applications

The antenna is ideal for wireless communications, FPV systems, radio communication, satellite applications, and projects where low weight and compactness are important. Right-hand circular polarization (RHCP) reduces interference from reflected signals and enhances compatibility with adjacent systems. The 6-turn design provides a narrow and stable beam range, making it an optimal choice for applications with critical data reception and transmission quality.

Model Features

• Frequency range: 4.9-6.1 GHz.
• Gain: 10 dBi — high sensitivity for long distances.
• Polarization: Right-hand circular (RHCP) — reduced interference and enhanced compatibility.
• Number of turns: 6 — optimal geometry for a stable signal beam.
• Beam angle: 100° — balance between directionality and coverage.
• Connector: SMA — convenient connection to standard equipment.
• Material: Plastic — lightweight and durable construction.
• Size: 70*52*85 mm; weight: 38 g — compact and lightweight for mounting on drones and other devices.

Technical Specifications

The Helical antenna combines ease of installation, versatility of applications, and high efficiency. It is suitable for both professional installations and amateur projects: unmanned aerial vehicles, stationary receiving points, mobile communication systems, and FPV kits. The SMA connector allows for easy integration of the antenna into existing systems, and the plastic casing provides reliable protection with minimal weight.

The model from — is a well-thought-out solution for those who value quality, reliability, and signal stability. Helical antennas can be purchased in our online store Flash Army; this antenna will be an excellent choice for tasks requiring high gain and stable circular polarization.
