Tactical amplifier system: Sky Rage Berkut remote antenna + AvengeAngel repeater + 40m WL400 cable
In modern warfare, the survivability of a UAV operator and the success of a mission directly depend on two factors: the ability to operate from deep cover and the ability to penetrate enemy electronic warfare (EW) systems. The professional Sky Rage Berkut system with the AvengeAngel repeater is the ultimate solution, allowing you to move the emitting part up to 40 meters from the console while maintaining a colossal signal power of 10 W per channel.
Why is this system the standard for professional aerial reconnaissance?
The main problem with remote systems is signal power loss in long cables. This kit is designed as a single ecosystem, where each element compensates for attenuation and maximizes data transmission efficiency.
- Dual gain: The AvengeAngel repeater acts as an intermediate station ("booster"), which prepares the signal for transmission along a 40-meter highway, and the Berkut antenna delivers the final 10 watts of power.
- Range and safety: Thanks to two sets of WL400 cables of 20 meters (a total of 40 m), the pilot can be in a buried dugout or concrete shelter, while the antenna operates on a high mast.
- Professional WL400 cables: Low loss coaxial cable minimizes signal degradation at 5.8 GHz frequencies, which is critical for stable video stream.
- Compatibility: Works perfectly with DJI Mavic 3, 3T, Matrice 30/300/350 series and Autel EVO II.

The Role of the AvengeAngel Repeater in the System
The AvengeAngel repeater plays a key role in the communication chain. It compensates for the losses that occur when the signal passes through 40 meters of coaxial wire. Without the repeater, the signal strength at the antenna input would be insufficient to fully activate the Berkut amplifiers. Together, they create a seamless "bridge" between the remote control and the drone.
Advantages of WL400 N-type cables
The WL400 cable is an analogue of the LMR-400 and is considered The "gold standard" for tactical communications. It features double shielding and a pure copper center conductor, which allows for the transmission of a high-frequency 5.8 GHz signal over long distances with a minimal standing wave ratio (SWR).
- Electronic warfare countermeasures: An output power of 40 dBm creates a stable channel that is extremely difficult to jam with standard trench electronic warfare means.
- HD video without lag: A low noise figure (<2.0 dB) ensures a smooth picture even at extreme flight distances (up to 20-25 km).
- Mobility and endurance: The system operates over a wide voltage range (6-12 V) and is protected from difficult weather conditions.
Important for units: The use of a 40-meter cable route allows the operator position and the emitting point to be dispersed. This significantly complicates the work of enemy electronic reconnaissance (ELINT) systems in finding the pilot's direction.
Conclusion: Technological dominance on the airwaves
The Sky Rage Berkut + AvengeAngel kit is professional equipment for those who do not compromise. You get maximum range, complete safety of personnel, and communication stability that saves equipment and ensures the completion of combat missions.
Frequently asked questions about the Sky Rage Berkut + AvangeAngel + WL400 kit
What is the role of the AvangeAngel repeater in this kit?
The repeater works as an active amplifier "in the gap". It receives the signal from the remote control, amplifies it, and transmits it along a 20-meter cable to the Sky Rage antenna. This is critically important, since without the repeater, a significant part of the remote control's power would simply be lost in the long cable.
How is this kit better than a regular antenna on the remote control?
The main advantage is safety and stability. The operator can be located in a shelter (dugout, basement, car), and the Sky Rage antenna will be moved 20 m to a high point. This provides a better line of sight with the drone and protects the operator from detection by radio signal.
What frequencies does the system with the AvangeAngel repeater support?
The kit is multi-band. It effectively amplifies signals at frequencies of 2.4 GHz and 5.8 GHz, and the Sky Rage antenna additionally supports 5.2 GHz, which makes the system universal for DJI Mavic 3, Matrice and Autel.
Why are WL400 cables used?
WL400 cables are the "Low Loss" standard. They are thicker and higher quality than standard cables, allowing for 20m signal transmission with minimal attenuation, which is especially important for the 5.8GHz frequency.
Is the kit compatible with the new DJI RC2 (Air 3/Mini 4 Pro) remote controller?
Yes, provided the remote controller is modified and has SMA connectors installed. The AvangeAngel repeater successfully amplifies DJI's digital data transmission protocols.
How do I properly charge this kit?
The Sky Rage antenna and AvangeAngel repeater each have their own batteries. They need to be charged separately via USB-C ports. We recommend using a Fast Charge power supply for faster charging in the field.
Can I use only one cable if the drone only operates on 5.8 GHz?
Technically, it is possible, but the system is designed to operate using MIMO (dual-channel transmission) technology. For maximum stability and range of the video signal, both cables must be connected.
How does a repeater affect operation in electronic warfare environments?
The AvangeAngel repeater, together with the Sky Rage antenna, creates a powerful output signal of up to 10 watts, which allows you to "break through" the jamming of enemy electronic warfare systems, where a conventional remote control would instantly lose connection.
What should I do if the signal deteriorates after connecting the cables?
Check that the N-type connectors are tightly tightened. Even slight insufficiency can lead to a loss of up to 50%. Also, make sure the repeater is turned on and charged.
What is the system power-up sequence?
It is recommended to first connect all the cables (Remote Control & Repeater & Antenna), and only then turn on the power on the repeater and antenna. This will protect the active components from overload.
