The frequencies comprising the microwave spectrum extend from approximately 1,000 megahertz, or 1 gigahertz, to approximately 50,000 megahertz, or 50 gigahertz. The upper end of this range is somewhat undefined, and indeed unpioneered, when visualized in respect to general amateur applications . A list of amateur frequencies available is shown in Fig. 1-3.While the 144, 220, and 432 MHz allocations are not microwave frequencies, they are included here as a reference to known and established amateur areas. Likewise, the MDS and satellite TV bands (2.1 and 4 GHz) , are shown as a means of familiarizing the amateur with the microwave spectrum.
