Yagi-Uda Lite 915 Antenna is an antenna designed to extend range and improve signal quality in digital or analog communication systems, with linear polarization.
UYA Lite 915 by BlueBird Tech is an ultra-lightweight and highly efficient antenna.
It is designed to operate in the 870–1000 MHz frequency range and is optimized for a 915 MHz center frequency.
The main advantage of the Lite version is its minimal weight while maintaining high mechanical rigidity.
The antenna base is made of heat-resistant PETG plastic, ensuring precise element positioning and stable technical performance even under vibration or wind loads.
The active antenna elements are made of brass, providing high electrical conductivity and corrosion resistance.
Thanks to its directional radiation pattern (≈60–85°) and a gain of up to 9 dBi,
UYA Lite 915 significantly increases signal transmission range and ensures reliable communication in the specified direction.
The antenna is designed to substantially extend operational range and improve signal quality for digital or analog communication systems.
Due to its ultra-low weight (≈75 g), it is an ideal solution for installation on relay drones, where minimizing payload is critical to preserve flight time.
The antenna is also effectively used in mobile ground relay systems and remote relay setups.
UYA Lite 915 is fully compatible with ELRS, Crossfire, and other telemetry and control systems operating in the 900 MHz frequency band.

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.
