The HELIX Lite 5.8/18 antenna by BlueBird Tech is an ultralight, high-precision helical antenna, specifically designed for applications where mass is critical and maximum radio channel stability is required.

The device operates in a wide frequency band of 4.9 – 6.1 GHz and transmits/receives signals with Right-Hand Circular Polarization (RHCP).

Technical Configuration and Advantages

1. High-Efficiency Radiator (18 turns)

The design is based on 18 precisely calculated helical turns, providing a high gain of up to 16 dBi.

This geometry forms a single-lobe, narrowly directional radiation pattern along the antenna's axis, with a main lobe width at -3 dB (HPBW) — only 27°.

This ensures increased range and effective isolation from background interference outside the main beam.

2. Lightweight and Mobile (Lite Concept)

A key emphasis in the design is placed on weight minimization.

This makes the HELIX Lite 5.8/18 ideal for use on mobile platforms — UAVs and repeater drones, where every gram matters, while maintaining mechanical reliability.

3. Stable Circular Polarization

High polarization quality (Axial Ratio < 1.5) ensures signal stability even during rapid movement, rotation, or operation in conditions of strong multipath propagation.

4. Versatile Mounting

Thanks to its thoughtful design and low mass, the antenna is equally convenient for mounting on stationary repeaters (masts, towers) and can be quickly integrated into onboard systems of mobile objects.

The HELIX Lite 5.8/18 combines engineering simplicity, minimal load on the carrier, and precise technical specifications required for professional long-range systems.
