Table of Radio Frequencies

Ok, as promised, here are the classifications of radio frequencies developed in a simple table, giving the Classification, Abbreviation and the Range of each frequency band.

Classification Abbreviation Range

1.) Very Low Freq. vlf or VLF 10-30khz/second

2.) Low Freq lf or LF 30-300khz/second

3.) Medium Freq mf or MF 300-3,000khz/second

4.) High Freq hf or HF 3,000-30,00khz/second

5.) Very High Freq vhf or VHF 30-300mhz/second

6.) Ultra High Freq uhf or UHF 300-3,000mhz/second

7.) Super High Freq shf or SHF 3,000-30,00mhz/second

8.) Extremely High Freq ehf or EHF 30,00-300,000mhz/second

Note: K = 1000 or Kilohertz
M= 1000000 or Megahertz
HZ= Hertz or cycles

Each of these frequency bands are used for different types of communications. Example: The high frequency (HF) portion from 3,000 to 30,000khz, is where the Amateur Radio operations are permitted, based on the type or class of licence each station holds. There are also different classes of station licences which determine what portion of a particular band that each station may operate in. More on this subject in a later session.
