The Motorola RDU4100 two-way radio packs a punch with 10 channels, 4 watts of power, and provides coverage up to 350,000 square feet or 30 floors. Supporting 89 UHF frequencies with 122 private line codes, the Motorola RDU4100 business radio allows the user to assign channels to any of the built-in frequencies and PL codes. The RDU 4100 radio also features channel scan, hands-free VOX mode (optional accessories needed), voice scrambling, revchargeable, low battery, and so much more. This Motorola RDX series radio was built for use in the construction, education, hospitality, manufacturing, property management, and retail fields.

The RDX series brings workplace noise to its knees by helping to ensure exceptional audio quality in the loudest environments. Designed for noisy areas, our radios are 30% louder than previous Motorola XTN and AX models as a result of new design enhancements. This business-essential radio provides the perfect partnership of excellent audio and exceptional durability.

Built Tough to Last

If you're looking for a tough radio, then the RDU4100 UHF Two-Way Radio is what you need. Meeting military specifications, the RDU4100 protects against dust, wind, shock, vibration, and other elements. This Motorola RDX Series Radio can take a beating and keep on giving you crystal clear communication for years to come. 

Diversified and Effective

The RDU4100 operates on UHF frequencies giving it the diversity of operating indoors and outdoors. The UHF waves allow for your signals to penetrate through wood, steel, concrete, and vertically up and down floors of a building. This ability of flawless communication is what makes the Motorola RDU4100 business radio the preferred choice of schools, factories, office buildings, and construction sites.

Smart and Efficient Accessories

Cut down on the clutter of several charging stations and wires at your office or work site. Pick up the RDX Series 6-Bank Charger to power up all of radios at the same time on one convenient charging station. It also acts as a cloning station allowing for you to mass program all of your radios at once (programming cable required).

Powerful and Durable Radio 

Within the Motorola RDX Series two way radios, the RDU4100 is a powerhouse of 4 watts of power built into a reasonable polycarbonate overmold weighing in at 10.3 ounces, 4.5 inches by 2.2 inches by 1.8 inches. That's some serious power for such a conveniently sized radio that easily fits on your belt or in a holster. The RDU4100 was built without an LCD display allowing for some rough usage on the product floor or out in the grit at the construction site.

Repeater Capability

Compatible with duplex repeaters so you can significantly extend your radio coverage area.

Rugged and water-resistant

Meets military specifications for sealing against dust, wind, shock, vibration and other adverse conditions.
