The Main Amateur Radio Bands
VLF ( Very Low Frequencies) 130 kHz to 530 kHz with power output limited to 5 watts
E.I.R.P Maximum. All other bands: You are allowed to use 1000 watts of power
HF (High Frequencies)
80 metres 3.5 to 3.9 MHz
40 metres 7.0 to 7.3 but 7.2 to 7.3 MHz is shared with other services
20 metres 14.0 to 14.35 MHz
15 metres 21.0 to 21.45 MHz on a primary basis
10 metres 28.0 to 29.7 MHz
6 metres 50 to 51 MHz only available subject to special conditions
51 to 53 MHz which is shared with another service
HF (WARC Bands) Allocated WARC 1969
30 metres 10.100 to 10.150 MHz
17 metres 18.068 to 18.168 MHz
12 metres 24.890 to 24.990 MHz
VHF (Very High Frequencies)
2 metres 144 to 148 MHz ], but 146 – 148 MHz is shared with other
communication services
UHF (Ultra High Frequencies)
70 cm. 430 to 440 MHz
23 cm – And many more UHF and SHF Bands above UHF
Notice the harmonic relationship between the various HF bands.
When the frequency in MHz goes up (Higher frequency), the wavelength in meters goes down.
And that makes sense when you look at the actual lengths of the antennas. At VHF and UHF frequencies the antennas are very short indeed.
