UYA Lite 915 by BlueBird Tech — is an ultralight and highly efficient Yagi-Uda directional antenna.

It is designed to operate in the frequency range of 870–1000 MHz and is optimized for a center frequency of 915 MHz.

The main advantage of the Lite version is its minimal possible weight while maintaining high mechanical rigidity.

Design and Materials

The antenna's base is made of heat-resistant PETG plastic, ensuring precise element fixation and stability of technical characteristics even during vibrations or wind loads.

The active elements of the antenna are made of brass, which guarantees high conductivity and corrosion resistance.

Radio Engineering Characteristics

Thanks to its directional pattern (≈60–85°) and gain of up to 9 dBi,

UYA Lite 915 significantly increases signal transmission range and ensures reliable communication in the specified direction.

Purpose

The antenna is designed to significantly increase the range and improve the signal quality of digital or analog communication systems.

Due to its ultra-low weight (≈75 g), it is an ideal solution for installation on drone repeaters, where minimizing the load on the device is critically important to preserve flight time.

The antenna is also effectively used as part of mobile ground repeaters and remote systems.

UYA Lite 915 is fully compatible with ELRS, Crossfire protocols, and other telemetry and control systems operating in the 900 MHz frequency band.
