Answer: There are two methods of measuring CB output, which were developed/adopted by the FCC. The old method measured signal strength into the final output circuit of the radio, and the maximum allowable was 5 watts. The new method measures output coming off the antenna. Because the radio consumes approximately one watt when operating, the maximum allowable at the antenna is 4 watts.
This radio was designed to provide the maximum allowable power. The number on the box refers to the old method, and the specifications list showing 4 watts is based on the newer method.
