Helical Antenna 3.3 GHz (light) 12dBi

The Helical Antenna (spiral antenna) from the manufacturer is a lightweight, compact, and highly efficient circular antenna designed for stable signal reception and transmission in the 3.0-3.5 GHz range with a central operating frequency of approximately 3.3 GHz. The "helix" design ensures high directivity and excellent signal stability over long distances, making this model an optimal choice for radio communication, satellite systems, wireless video, and FPV solutions.

The model is marked as light, emphasizing its compactness and minimal weight — only 50 g, with dimensions of 80*80*330 mm. Its low weight and size allow for easy mounting on drones, portable devices, and light platforms where mass and ease of attachment are critical.

Technical Specifications

Advantages and Applications

• High gain of 12 dBi ensures stable communication over long distances and increased transmission range.
• Right-Hand Circular Polarization (RHCP) reduces interference and improves reception quality in multipath environments.
• Compact and lightweight (light) design is ideal for installation on drones, mobile platforms, and portable equipment.
• Durable plastic casing ensures longevity in outdoor use and resistance to mechanical stress.
• Universal SMA connector guarantees compatibility with a wide range of transmitters and receivers, simplifying integration into existing systems.

The Helical 3.3 GHz (light) antenna combines low weight, reliable circular polarization, and high gain, making it an excellent choice for radio communication, FPV systems, unmanned platforms, and satellite solutions where signal directivity and stability are important. The 10-turn design with a 45-50° beam angle provides an optimal balance between beam focusing and spatial coverage.
