1、Frequency Range: The transceiver has all 40 CB channels and can go from 26.965 to 27.405 MHz, stable and reliable. 2、Portable Design: The CB transceiver is lightweight, ultra thin and easy to carry, giving you an excellent use experience. 3、Stable Connection: You can install the transceiver in any location where 12‑16V DC power is available, and it can be connected to either the negative or positive terminal. 4、Fuse Replacement: If replacing a fuse in the DC power cord, use a 2 amp type (one as a spare). Hold the fuse holder and press inward, then rotate the fuse holder. 5、Performance: Antenna length is directly related to the efficiency, the longer the time, the higher the efficiency, please make sure your antenna is compatible with the machine.
