Installing Your Handheld DMR Race Radio
What You Need
- Your DMR handheld radio
- A suitable mounting location in the car
- Optional: adhesive mounting pad or small bracket
- Optional: cable ties or velcro straps for cable management
Installation Steps
1. Choose Your Mounting Location
Select a spot where the driver can easily reach and operate the radio without taking their hands off the wheel for extended periods. Common locations include:
- Dashboard (secured with adhesive pad)
- Roll cage (cable-tied to a suitable bar)
- Door panel or A-pillar
- Center console
Avoid locations where the radio could become a hazard in a crash or obstruct controls you need during the race.
2. Mount the Radio
Using an adhesive pad:
- Clean the mounting surface with a dry cloth
- Apply the adhesive pad to the back of the radio or mounting bracket
- Press firmly in place and let it set (follow pad instructions for cure time)
Using cable ties or velcro:
- Secure the radio to your chosen location with cable ties or industrial-strength velcro straps
- Ensure it's snug and won't rattle or move during driving
3. Position the Antenna
- Keep the antenna vertical or slightly angled for the best reception
- Avoid positioning it where it could break or interfere with the driver's movement
- If using a handheld, the antenna should point upward from the radio
4. Test Before Race Day
- Turn on the radio and confirm it powers up
- Check that your team can communicate on the correct channel
- Test range and clarity from the driver's position in the car
- Confirm the driver can operate it safely without distraction
Important Notes
- Keep the radio accessible but secure—it shouldn't move around during hard cornering or braking
- Test communication with your pit crew or chase vehicle before heading to the track
- Make sure the driver knows how to transmit and receive before race day
- Check that the antenna won't be damaged by roll cage bars or other components
