Feature: 1. Dual Band: LCD screen, the upper and lower sides of the screen can display the UV dual band frequency, no matter which frequency band has a signal, it can be received. 2. 25W High Power: Mobile vehicle radio is equipped with new circuit optimization technology to create excellent characteristics of low energy consumption and strong penetration. 3. Good Heat Dissipation: The external DC heat sink of the host, with the temperature controlled cooling fan, can ensure that the radio circuit is within the safe temperature range. 4. With Microphone: Equipped with handheld microphones, the numeric keyboard can directly input the operating frequency, and get rid of the trouble of writing frequency. 5. Communication Distance: Measured in open suburbs: 8‑16KM can stably communicate; Measured in high buildings: 6‑13KM can stably communicate, convenient for using.
