Portable 150M and 400M Relay Station（150M/400M）
一、Overview
Portable 150M/400M relay station, also known as “temporary ground communication dispatching and command system”, is mainly used to solve the need for staff to temporarily set up and network in the coverage area when using walkie talkies to deal with emergencies, complete communication dispatching, coordinate command and emergency rescue work.
Portable relay station appearance, as shown below.
二、Characteristic
1. Multiple operating modes: conventional digital mode (DMR double time slot), conventional analog mode. Cluster controller can be optionally configured to work in DMR cluster or PDT cluster mode.
2. Modular structure: the stacked modular design is adopted to facilitate the configuration of large capacity batteries as required. Built in duplexer.
3. Reliable industrial design: adopt aluminum alloy CNC processing technology, and the structure is solid. Aviation plug is adopted, with rainproof design. The unique frame protection design effectively protects the interface, panel and body.
4. Convenient interactive interface: 2.2 "semi transparent full-color LCD screen is used to display more information, and rich functional operations are realized with direction keys.
