HELIX Lite 5.8/18 Antenna is an antenna for signal transmission and reception with circular (right-hand) polarization.
The HELIX Lite 5.8/18 antenna by BlueBird Tech is an ultra-lightweight, high-precision helical antenna specifically designed for applications where low weight is critical and maximum radio link stability is required.
The device operates over a wide frequency range of 4.9 – 6.1 GHz and transmits/receives signals with Right-Hand Circular Polarization (RHCP).
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, narrow-beam radiation pattern along the antenna axis, with a main lobe width at −3 dB (HPBW) of only 27°.
This ensures extended operating range and effective isolation from background interference outside the main beam.
2. Lightweight and mobility (Lite Concept)
The key design focus is on weight minimization.
This makes the HELIX Lite 5.8/18 ideal for use on mobile platforms such as UAVs and relay 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 environments with strong multipath propagation.
4. Universal mounting
Thanks to its well-engineered design and low weight, the antenna can be easily mounted on stationary relay systems (masts, towers) and quickly integrated into onboard systems of mobile platforms.
HELIX Lite 5.8/18 combines engineering simplicity, minimal payload load, and precise technical characteristics required for professional long-range communication systems.

An omnidirectional antenna provides coverage “all around,” while a directional antenna focuses and amplifies the signal in a specific direction and usually offers greater range.
Refer to the operating frequency range of your system (for example, 1.2 GHz / 5.8 GHz / 750–915 MHz).
Yes, lighter antennas have less impact on autonomy and controllability.
Yes, some models are designed for drone repeaters and ground-based relay nodes.
They allow the receiving point to be placed in a better position and improve reception quality and range in compatible systems.
