One of the big differences between CB and HAM radio is that in HAM radio you have to deal with the equivalent of thousands of CB channels.
The spectrum consists of many different bands. Each frequency has an associated antenna length. You can have several antennas of varying lengths that are sized to operator on these bands, then you can manually switch them as you change bands on your radio.
Then came automatic antenna tuners!
With the press of a button the automatic antenna tuner takes one antenna and matches it to the radio so you can use it in just a few seconds.
