The Shpak Drone Repeater Kit (DRK) is an airborne retransmission system that overcomes the radio horizon – the fundamental limit of every ground-based antenna. By elevating the FPV control and video link above terrain obstacles, the DRK extends FPV operations across forests, hills, urban structures, and fortified positions and improves signal reliability in EW-contested environment.
Bypasses forests, hills, urban clutter, trenches, and fortifications.
Stable control and video transmission up to 25 km in mixed terrain.
Elevated link reduces exposure to low-mounted jammers and terrain-induced interference.
Concealed operation from bunkers, dugouts, treelines, or covered positions.
Full modular replacement of VRX, VTX, control TX, antennas, and battery – five minutes, no tools.
In active combat use with Ukrainian units. In service with the Lithuanian Armed Forces.
The DRK is engineered as the native communication backbone for the Shpak FPV drone family. The RTK mounts on a separate drone carrier capable of lifting an 800-gram payload, positioning itself between the operator’s MAR on the ground and the Shpak drone in flight. The DRK’s modular transmitter architecture and broad frequency range also support compatibility with third-party FPV drones.

The DRK consists of a Repeater Unit (RTK) mounted on a carrier drone, and a Mini Antenna Rack (MAR) operating from the ground. Together they form a deployable virtual mast – positionable anywhere, mountable on any compatible carrier.
A lightweight, swappable-module airborne payload providing high-elevation, low-latency relay for both video and control channels.
A compact, rugged, weatherproof ground interface designed to remain deployed and unattended between missions.
