Feature: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 1216V 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.Specification:Item Type: CB TransceiverMaterial: Metal.Parameter Information:Frequency Range: 26.965 to 27.405 MHz for all 40 CB channelsModulation Mode: AM modulation (A3)Required Power Supply: 12-16 V DCAntenna Impedance: 50 ohmsOutput Power: 1WModulation Capacity: 80-90%Spurious Emission: 62dB or betterFrequency Tolerance: Better than 0.002%Current Consumption (13.8V) :1.3 amps (no modulation)2.0 amps (full modulation)Sensitivity: 1.0V or better for 10dB S+N/NAdjacent Channel Inhibition: 60dB (at 10KHz) > 70dB (for 20KHz)Intermediate Frequency: 1st IF = 10.695MHz, 2nd IF = 455KHzAudio Output: 4.5 Watts maximumFrequency Response: 450-2500HzCross Modulation: 45dB or betterNoise: Adjustable from 1.2V to 1mVTransmitting Power: 1WPackage List:1 xCB Transceiver1 x User Manual1 x Mounting Bracket 2 x Accessories Pack (7PCS)1 x Fitting Pipe Note:1.
