UDM-240 Combo Series 2-in-1 Communication

UDM-240ZH Wireless Speaker Mic & UDM-240ZV Mobile/Base Station Repeater
UDM-240ZV Interfaces to all major brands of Mobile Radios through an RJ-45 cable connection.

The UDM Series provides both mic to mic and/or repeater mode communications. Ideal for dispatch centers, toll booths, small offices, electrical/tower crews, tow-truck/sanitation trucks, or anywhere you need to stay connected and need a tough wireless mic to communicate. When our UDM System’s UDM-240ZV repeater is tethered to your vehicle’s mobile radio or office base station, the UDM-240ZH palm mic can function as a tough, wireless PTT mic for the mobile up to 320’ away. While in wireless communication with your mobile radio using one PTT button, you will also have the ability to have a private conversation to other UDM mics 160’ away from each other on a separate PTT button through its “Intercom” mode.

Package includes: UDM-240ZH – Wireless Speaker Microphone and Charger & UDM-240ZV – Repeater Interface Module, Antenna, and Interface Cables.
