The unit includes an integrated amplifier to enhance signal quality. Key electrical specifications include a supply voltage of 12V DC and a current consumption of 40mA. The DAB section operates at 1575.42±3MHz with RHCP polarization and 2dBic gain. FM/AM ranges cover 520~1629KHz and 174~237MHz/1452~1492MHz respectively. Cable lengths vary between 1.5 meters and 3 meters in different configurations.

Feature Summary

• Combines DAB, FM, and AM radio reception in a single roof-mounted unit
• Integrated amplifier ensures stable signal processing and clear audio output
• Screw mounting design provides secure attachment to vehicle surfaces

Applications

• Vehicle roof installation for automotive radio systems
• Camping vehicles requiring multi-band radio reception
• Automotive aftermarket radio upgrades

Procurement Notes

Verify the specific cable length configuration required, as sources indicate both 1.5-meter and 3-meter options exist for this model. Confirm that the 12V DC supply requirement matches your vehicle's electrical system. Ensure the screw mounting interface is compatible with your vehicle's roof structure before purchase.

Selection Notes

Select this component when a unified solution for DAB, FM, and AM reception is needed without separate antenna installations. Consider the integrated amplifier feature if signal strength in your area is weak. Verify the specific frequency bands supported, particularly for DAB BⅢ/L-Band compatibility if operating in regions using those standards.

Part Context
