The company said the Drone Repeater Kit is already in active combat use with Ukrainian units. It is also in service with the Lithuanian Armed Forces.
The system consists of two integrated components. These are a Repeater Unit mounted on a carrier drone and a Mini Antenna Rack operating from the ground.
Together, the components raise the FPV control and video link above terrain obstacles. RSI Europe said the system can restore stable communication where forests, hills, urban structures or fortified positions limit the performance of ground antennas.
The Drone Repeater Kit serves as the native communications backbone of RSI Europe’s Shpak FPV family. It completes an integrated mission-ready capability combining strike drones, ground control and airborne retransmission engineered to operate together.
The system is also compatible with third-party drone platforms. RSI Europe said the design supports wider use beyond its own FPV drone family.
The Drone Repeater Kit was developed in response to operational requirements identified through direct feedback from Ukrainian FPV operators. The company also used evaluations conducted with allied units.
The system addresses range, terrain, electronic warfare resilience and operator survivability constraints linked to ground-based antenna setups in active sectors. It is intended to allow FPV teams to maintain more reliable communications while remaining in concealed positions.
“What the DRK gives an FPV team is the ability to operate from concealed positions and still maintain a stable link beyond terrain obstacles. The repeater goes where the team can’t — over a hill, above a treeline, into clean line-of-sight — while the operators stay where they’re safe,” said Martynas Antanaitis, Product Manager at RSI Europe.
RSI Europe said the Drone Repeater Kit can provide an operational range of up to 25 kilometres in mixed terrain. Stable line-of-sight is maintained from altitude to support FPV operations beyond physical terrain barriers.
The company said the system improves electronic warfare resilience by preserving more of the link’s signal margin against jamming through clean line-of-sight from altitude. Its Mini Antenna Rack is IP67-certified, comes in a suitcase form factor and uses a 50-metre cable to allow operators to remain concealed.
The Drone Repeater Kit includes transmitters compatible with third-party drones and broad frequency coverage. It also features LED-based link confirmation across each leg of the communication chain, single-button pairing and a setup time of 5 to 10 minutes.
