Motorola RDU4163D UHF Business Two-Way Radio
RDX Series • UHF • 4 Watt • 10 Channel Display • Licensed Radio
The Motorola RDU4163D was a 4-watt UHF display radio from Motorola's RDX Series, built to give crews, retail floors, and warehouse teams a rugged, business-grade communication tool. Because the RDU4163D operates on professional UHF business frequencies, a Canadian ISED radio licence may be required. This model has since been discontinued — see the current business two-way radio lineup for an active replacement.

Recommended Replacement
The Motorola RDU4163D has been replaced by the Motorola CP100d. The CP100d is the current Motorola business UHF radio that carries the RDX/RDU lineup forward, and it is the model we recommend for new fleets and for adding to existing RDU4163D deployments. View the Motorola CP100d for full specifications, or browse compatible CP100d accessories to outfit your team.
Who Was the Motorola RDU4163D For?
The RDU4163D suited businesses that needed a licensed, display-equipped UHF radio for everyday on-site coordination — retail, hospitality, light industrial, warehousing, and property teams. Because it ran on professional business UHF frequencies, a Canadian ISED radio licence may be required, which is standard for this class of radio.
If you previously ran RDU4163D handsets, the Motorola CP100d is the direct path forward. You can also compare the full range of current commercial two-way radios to match your coverage and team size.
