Signal Amplification System: Sky Rage Berkut Remote Antenna + AvengeAngel Repeater + 2 × 20 m WL400 Cable Sets
The Sky Rage Berkut system with the AvengeAngel repeater is designed for a remote signal transmission system with the antenna positioned up to 40 meters away from the main equipment. The kit includes an active remote antenna with an amplifier, a repeater, and two 20-meter WL400 coaxial cables.
Key Features of the System
The system combines an active antenna, repeater, and low-loss cables to provide stable signal transmission. The use of a remote antenna allows flexible equipment placement depending on operating conditions.
- Active amplification: The AvengeAngel repeater is used as an intermediate element of the signal transmission system, while the Berkut antenna features a built-in amplifier.
- Cable length: Two 20-meter WL400 cables can provide a total cable line length of up to 40 meters.
- WL400 cables: Low-loss coaxial cables are designed for high-frequency signal transmission and reduced signal attenuation.
- Compatibility: The system is designed for use with DJI Mavic 3, 3T, Matrice 30/300/350, and Autel EVO II equipment.

Role of the AvengeAngel Repeater in the System
The AvengeAngel repeater serves as an intermediate element of the signal transmission system. It is used to amplify the signal before it is transmitted through the coaxial cable line to the remote antenna. This configuration allows the main equipment, repeater, cables, and antenna to operate as a single integrated system.
Advantages of WL400 N-Type Cables
The WL400 cable is an LMR-400 equivalent designed for high-frequency signal transmission with low signal loss. The cable features double shielding and a pure copper center conductor, providing stable transmission characteristics within the supported frequency range.
- Low signal loss: The WL400 design provides low attenuation when transmitting signals through long cable lines.
- HD signal transmission: The low noise figure of the system contributes to stable data and video signal transmission.
- Versatile operation: The system supports a wide voltage range of 6–12 V and is designed for use in various operating conditions.
