The tri-band portable signal booster AvengeAngel is a high-performance antenna system designed for use with a wide range of unmanned aerial vehicles, including FPV drones and commercial UAV platforms. Developed based on real operator experience and inspired by well-known antenna solutions, it delivers improved signal quality, mobility, and operational flexibility in field conditions.
The antenna operates across three frequency bands - 2.4 GHz, 5.2 GHz, and 5.8 GHz - ensuring compatibility with most modern drone control and communication systems. It supports IEEE 802.11 B/G/N/AC standards and utilizes advanced transmission methods such as DSSS (Direct Sequence Spread Spectrum) and OFDM (Orthogonal Frequency Division Multiplexing), which enhance signal stability in challenging RF environments.
The integration of TDD (Time Division Duplex) technology with linear power amplifiers allows for extended communication range without compromising transmission quality. High-power amplifiers (up to 10W each) significantly improve both signal transmission and reception, ensuring stable connectivity over long distances. The system also supports widely used communication protocols, including Wi-Fi and OcuSync.
The AvengeAngel antenna improves UAV operational performance by increasing communication range and enhancing control stability. Field tests indicate improved signal reliability and reduced latency compared to standard antenna setups. Under favorable conditions, drones can achieve significantly extended operational distances depending on configuration.
The antenna can be deployed at a distance from the operator to improve signal positioning flexibility, or placed in open areas to optimize coverage and signal quality. One of its key advantages is extended autonomous operation - up to 12 hours of continuous use - making it suitable for long-duration inspection, mapping, and monitoring tasks. The IPX68-rated housing ensures reliable performance in harsh environments, including rain, moisture, and dust.
The system supports frequency ranges of 2400-2500 MHz and 5000-5875 MHz and is equipped with dual tri-band power amplifiers rated at up to 10W (40 dBm). It offers a gain of 20-22 dB with a noise figure of ≤2.0 dB, ensuring high signal clarity. Antenna gain is approximately 15 dBi at 2.4 GHz and 18 dBi at 5.8 GHz.
The radiation pattern provides coverage angles of about 65° horizontally and 20° vertically, enabling directional signal optimization. The device operates on 6-12V and includes a 7.4V 6400 mAh battery. It uses an N-K Female connector and weighs approximately 1680 g, making it portable and suitable for field deployment in professional UAV operations.
