MAVKA 2E ROC4 Remote tri-band active directional antenna 2.4/5.2/5.8GHz, 10W, for DJI, AUTEL(V2), FPV is a portable signal booster widely used in the UAV field and for Wi-Fi connectivity to significantly improve link stability between a drone and its controller while increasing effective operating range. The model is compatible with controllers modified for Alientech, including setups such as “Avengers”, “ForHawks”, “Alisa”, and similar solutions (when used with 2E cables and 2E adapters). With 10 W (40 dBm) output power, strong amplification, and quality directional antennas, the device helps maintain a more reliable link at distance and in challenging RF environments. A rugged aluminum корпус and a high-capacity 8000 mAh battery enable practical field use, while the charge indicator and USB Type-C charging add everyday convenience.
🫡 We are a team of veterans
We treat equipment like this as a working tool where link stability, predictable behavior under interference, and operational reliability matter most. MAVKA 2E ROC4 is relevant when you need confident 2.4/5 GHz amplification and quick deployment in the field. For high-risk missions, correct installation is critical: proper 2E cables/adapters, secure N-Type connections, power control, and visual battery monitoring directly affect overall stability and performance.

💬 Commentary / comments
MAVKA 2E ROC4 is a practical amplification solution for 2.4 GHz and 5 GHz bands, intended for popular UAV ecosystems (DJI, AUTEL(V2), FPV) and for controllers modified to Alientech standards, provided that the correct 2E cables and 2E adapters are used. A low noise figure (<2.5 dB) is important for maintaining reception quality in real-world RF conditions, and the aluminum housing improves durability during transport and field use. From a technical standpoint, it is essential to respect the allowed input power range (3–23 dBm) and to ensure correct power/charging setup (5 V / 2 A via Type-C) to avoid instability under load.
🎯 Who it is suitable for
Primarily suited for military UAV operators, reconnaissance units, and special teams that need extended control/link performance at distance and reliable operation in complex RF environments. It is also suitable for professional drone operators, engineering teams, search-and-rescue units, and technical services requiring portable 2.4/5 GHz amplification and a robust field-ready design.
