Large, reinforced concrete structure fire and rescue in-build radio communications training exercise

...not the best environment for radio communications

C-AT ICRI-2PED MotorolaTM XTS5000TM, 800mHz MotorolaTM APX7000TM, 700MHz

Five 500’ C-AT CABLE-REELS

The use of a electrical slip-ring in the hub of the reel permits radio communications as the cable is unreeled.

Four 500’ cables connected with positive-lock, metal connectors Radio on the “lead” cable

No radio comms from here to the Incident Commander without the ICRI and cable-reels. Smoke added to the importance of providing the IC with real-time situational awareness.
