📝 Kit: Sky Rage Berkut External Antenna + Warmax Repeater + Two 20 m WL400 N-Type to N-Type Coaxial Cable Sets
The Sky Rage Berkut + Warmax repeater + two 20-meter WL400 cables kit is a professional remote signal amplification system for unmanned platforms that allows the antenna station to be placed at a significant distance from the operator’s working position. The system is built as a modular setup and includes a 10W active Sky Rage Berkut antenna, an intermediate Warmax repeater, and two low-loss WL400 N-Type to N-Type coaxial cables, each 20 meters long. This configuration makes it possible to build a cable path up to 40 meters with minimal signal degradation and to maintain stable communication over a considerable distance.
Sky Rage Berkut operates in the 2.4 GHz and 5.8 GHz bands and is compatible with many digital control platforms including DJI, Autel and other compatible unmanned systems. In this system, the Warmax repeater is used as an intermediate amplification node that helps maintain signal quality along a long cable line. The WL400 cables provide low attenuation and allow signal transmission over a long path without a sharp drop in effectiveness. As a result, the user gets a ready-made modular system for placing the antenna on a mast, rooftop, tripod or another optimal position.
🫡 We are a team of veterans
We are a team of veterans, and we understand that the effectiveness of an unmanned system depends not only on the drone itself, but also on the quality of the control link and video link. In real use, the correct organization of a remote antenna often provides a greater result than trying to strengthen the system with one separate module alone. If the signal passes through a long cable without proper loss compensation, even a powerful antenna cannot fully realize its potential.
That is why kits in which the antenna, repeater and cables are selected as one complete system have real practical value. We pay attention not only to amplifier power, but also to cable type, connector quality, layout logic, field stability and the convenience of rapid deployment. Such a kit allows the transmission point to be placed far from the operator, reduces the influence of terrain and obstacles, and makes the communication channel more predictable. For long-duration and responsible work, this matters a lot.

💬 Comment / comments
The key strength of this kit lies not in the antenna alone, not in the repeater alone, and not in the cable alone, but in the way they work together in one RF path. If a powerful antenna is simply connected through a long cable, part of the effectiveness is inevitably lost because of signal attenuation. In this kit, the Warmax repeater performs the function of intermediate signal support, while WL400 ensures low loss over a large distance. As a result, the system is better suited for remote installation than solutions assembled from random components.
Another important advantage is flexibility of deployment. The antenna can be installed separately from the operator’s working position, raised higher, or moved to a point with better line of sight. This makes it possible to build a more stable and convenient communication channel in difficult terrain, built-up areas or other physically obstructed environments. Such a kit is suitable both for a stationary site and for a mobile field configuration that must be deployed quickly on location. For real practical work, this gives a noticeable advantage.
🎯 Suitable for
Military personnel. This kit is suitable for units working with unmanned platforms that require a stable remote antenna station. The main advantage is the ability to place the antenna far from the operator’s working position while keeping the working point in a more protected or less visible location. This makes it possible to organize a field control point more effectively and reduce the influence of local obstacles on link quality. The modular layout of the kit is also convenient because it can be adapted to a specific position such as a mast, roof, tripod or another mounting point. For long-term and responsible work, this configuration is both practical and technically justified.
UAV and FPV operators. For drone operators, this kit is useful because it provides not just amplification but a complete remote RF path architecture. Two long cables and a repeater allow the antenna to be moved to a place where signal propagation conditions are better than directly next to the controller. This is especially useful in complex terrain, built-up areas, or whenever the operator’s position is not optimal in terms of line of sight. The active antenna provides strong output, while the repeater and cables help deliver that signal to the radiation point without severe losses. As a result, the user gets more stable system performance and a more practical deployment process.
Surveillance and security units. For observation tasks, this kit is suitable because it allows the antenna to be placed at an elevated or remote point while keeping the working position inside a shelter, building or other protected zone. This is useful for long duty shifts, area monitoring, perimeter control or operation from a stationary point. The presence of two 20-meter cables provides flexibility when building the path and allows the system to be adapted more easily to a specific location. The repeater included in the kit helps maintain a useful signal level even with a long remote placement. For real surveillance and security work, this makes the system significantly more convenient than short or incomplete configurations.
Technical specialists and radio operators. For technical specialists, this kit is valuable as a ready-made modular solution for building a long remote antenna line. It is suitable for field testing, experimental systems, technical benches and stationary or mobile radio complexes in the 2.4 and 5.8 GHz bands. N-Type connections, low-loss cables and the logically built scheme with an intermediate repeater make the system predictable from an engineering point of view. This matters for those who evaluate not only compatibility but also the actual RF path quality over a long distance. In this format, the kit is a practical tool for professional work with complex wireless systems.
