“We engaged a vehicle with active EW systems. Control was maintained until impact despite heavy interference. Thank you for your work!”

— callsign “Spalakh”, 411th Regiment “Yastruby”

“We used to fly on 490–510 MHz and we still do 🙂 Sometimes there is jamming, but we switch to 7 W and it keeps working without issues. We’ve already changed three operational directions and flying works great everywhere”

— callsign “Shelby”, 5th Separate Assault Brigade

“We used the coalas::45 system. It performs very well in our area of operation. Under favorable weather conditions, engagement range is limited only by battery capacity”

— callsign “Sova”, 3rd Separate Assault Brigade

“The Coalas communication system has shown strong results on our UGVs in combat conditions. We value the transmitter power, link reliability, and fast technical support from the manufacturer”

— UGV manufacturer T11

“In combat conditions, this communication system enables operations at a distance of up to 7 km without a repeater, with a 20 m elevation difference. To date, one successful casualty evacuation using a drone equipped with this link is confirmed”

— UGV manufacturer Targun

“Interesting systems — with the right approach and proper antennas, they deliver impressive ranges. Most importantly, they operate in low frequency bands, which perform well over complex terrain”

— UGV manufacturer SPEXTR
