THE RADIO IS A LIFELINE.
Mobile radios, control heads, microphones, speakers, antennas and in-vehicle connectivity, placed so the operator can talk without hunting for a control.
Roof, console and everything between.
Antennas need roof space and separation. Radios need a mounting location, power and cooling. Control heads and mics need to fall to hand. The cable runs connecting them are where good and bad installs show the difference.
From antenna to microphone.
Mobile radios
Dash, console or remote-mounted radios installed with clean power, grounding and service access.
Control heads + mics
Placed for reach and visibility from the operator's seat, and coordinated with lighting and data controls.
Antennas + cabling
Antenna placement and cable routing planned around roof equipment, ground plane and other radios.
Speakers + audio
External and in-cab audio positioned so traffic is heard over the siren and the cab stays usable.
Vehicle connectivity
Cellular routers and in-vehicle networking that keep mobile data and video connected. See Mobile Data.
Multi-radio vehicles
When the assignment calls for more than one radio or band, each one gets its own placement, power and antenna plan.
Clear audio starts with a plan.
Most communications problems in a vehicle aren't the radio. They're placement, power, grounding, noise and antennas competing for the same roof. These questions come first.
Operator Cockpit Checklist
Reach, sightlines, airbag zones and cable routing, checked from the driver's seat.
- Whose radio is it? New, agency-owned or moving from a retiring vehicle. Each one changes the plan.
- Which system and bands? The radio system your agency runs on decides antennas and how far apart they need to be.
- Where's the control head? Reachable while driving, and not in an airbag deployment path.
- What else is transmitting? Radios, routers and cameras sharing a roof need placement that avoids interference.
- What makes noise? Lighting, inverters and power circuits can add noise to audio if they're not planned for.
- Can it be serviced? Labeled cables and accessible connections make the next radio swap simple.
