In today's combat environments, communication channel stability and UAV operator safety are critical factors for mission success. ALIENTECH DUO II (model DUO-2458SSB) — This is a professional active dual-band antenna amplifier, which allows not only to increase the flight range several times, but also to provide a stable video stream in conditions of intensive operation of enemy electronic warfare (EW) equipment.
This system is designed for professional use with the DJI Mavic 3, 3T, Matrice 30/300/350 and Autel EVO series, providing "pushing" signal through dense interference and urban development.
Key advantages of ALIENTECH DUO II for tactical missions
Unlike passive solutions, ALIENTECH DUO II uses active power amplifiers, which allows compensating for losses in coaxial cables when the antenna is located at a safe distance from the pilot.
- Dual-band power: Effective amplification at 2.4 GHz and 5.8 GHz frequencies provides versatility for most modern quadcopters.
- Breakthrough electronic warfare: High transmission gain (15 dB) allows the control signal to remain stable even under the influence of enemy jamming equipment.
- Video stream clarity: Receive gain of 10 dB minimizes “freezes” and image breaks at long distances, which is critical for the accurate dropping or adjustment of artillery.
- Crew safety: The remote design allows the operator to work from deep cover, dugout, or armored vehicles, placing only the antenna on the mast or roof of the building.
Technical and tactical characteristics (TTX) of ALIENTECH DUO II
The DUO-2458SSB model is based on linear amplifiers with a low EVM (3%), which maintains a high data transfer rate without distortion.

Compatibility and Application
The ALIENTECH DUO II Antenna is the "gold standard" for upgrading remote controllers. It is compatible with the following platforms:
- DJI: Mavic 3, Mavic 3 Enterprise (3E, 3T), Matrice 300 RTK, Matrice 350 RTK, Matrice 30 Series.
- Autel: EVO II Series, EVO Lite, EVO Nano.
- FPV systems: Can be adapted for remote ground stations operating in the 2.4/5.8 GHz bands.
Expert tip: For maximum efficiency, use low-attenuation coaxial cables (such as WL-400 or RG-8) when extending the antenna beyond 10 meters. The low noise figure (<2.5 dB) allows the antenna to “hear” the drone even when the standard remote control has already lost connection.
Why choose ALIENTECH DUO II?
Unlike budget boosters, the DUO II provides stable linear amplification without signal distortion. This means,You don't just get "bars" of communication on the console, but a real working link capable of transmitting high-quality video over a distance of 10-15 km or more (depending on air conditions and antenna height).
