How far does CB radio reach?

The range of CB radio (Citizens Band Radio) depends on various factors, including the equipment used, antenna height, terrain and atmospheric conditions. In general, CB radios can achieve a range of up to 20 kilometers under ideal conditions and with good antenna systems. However, in urban areas with many obstacles, the range may be limited to a few kilometers. However, under certain atmospheric conditions, such as Sporadic-E or during sunspot maxima, CB radio signals can be received over hundreds of kilometers.
