We have had VHF and UHF amateur radio bands since the 1920s!  Before World War II the VHF bands followed the harmonic relationship of the HF bands.  In 1939 the bands above the 10-meter band were:

5 meter band:  56.0 MHz to 60.0 MHz
2.5 meter band:  112.0 MHz to 118.0 MHz
1.25 meter band:  224.0 MHz to 230.0 MHz
0.7 meter band:  400.0 MHz to 401.0 MHz

In 1946 the bands above 10-meters were:

6 meter band:  50.0 MHz to 54.0 MHz
2 meter bnad:  144.0 MHz to 148.0 MHz
1.25 meter band:  235.0 MHz to 240 MHz
0.7 meter band:  420.0 MHz to 450.0 MHz

and the UHF bands were:

1215.0 MHz to 1295.0 MHz
2300.0 MHz to 2450.0 MHz
3300.0 MHz to 3500.0 MHz
5650.0 MHz to 5850.0 MHz
10,000.0 MHz to 10,500.0 MHz
21,000.0 MHz to 22,000.0 MHz

Prior to World War II there were a number of mobile operations on both the 5-meter and 2.5 meter bands.

We didn't have VHF ham bands in the 50's, so all the mobile units that hams had were either on 10 or 80 Mtrs. So I could take a modified 455 and a Gonset converter and a 108 inch whip and be on the air.  Power was often a vibrator.

I used a Stancor 203-A transmitter with a Carter dynamotor, all in the trunk of the Kaiser, and the Gonset strapped to the stearing wheel. Hey, that surplus stuff was about the only way to go.
