The Motorola Model RDU4100 RDX Business Two-Way VHF Radio is just what you need on that job site. Whether indoor or outdoor, this radio delivers its crisp and audible signal with confidence. Versatile and rugged, the RDU4100 will not only provide clear audio transmission but will stand up to the most demanding physical conditions. Rain, wind, fog - this unit will withstand them all. Motorola built this water resistant unit with heavy duty on-site work in mind.
When profit is on the line and time cannot be wasted asking for repeated calls, why pay for an inferior radio which you will only have to replace? You'll make good use of this radio's channel selection and multi analog and digital code possibilities.
And, with the optional CPS (Computer Programming Software) interface, internal settings can be "tweaked" to suit your own needs. This is a solidly built radio at a more than affordable business price.
