RSI Europe · Supports System
“The DRK — Drone Repeater Kit — with two main components, the Mini Antenna Rack (MAR) and a Repeater Unit (RTK) is RSI Europe’s answer to this problem set. It is not a clean-sheet design but the product of iteration on Ukrainian operator feedback. A few features stand out as direct responses to known field requirements.”
