The 20-meter or 14-MHz amateur radio band is a portion of the shortwave radio spectrum, comprising frequencies stretching from 14.000 MHz to 14.350 MHz.[1] The 20-meter band is widely considered among the best for long-distance communication (DXing), and is one of the most popular—and crowded—during contests.[2] Several factors contribute to this, including the band's large size, the relatively small size of antennas tuned to it (especially as compared to antennas for the 40-meter band or the 80-meter band) and its good potential for daytime DX operation even in unfavorable propagation conditions.[3]
The Third National Radio Conference was responsible for opening up the 20-meter band to amateur radio operators in the US[4] on October 10, 1924. The band was allocated on a worldwide basis by the International Radiotelegraph Conference[5] inWashington, D.C., on October 4, 1927. Its frequency allocation was then 14–14.4 MHz. The allocation was reduced to 14–14.35 MHz by the International Radio Conference of Atlantic City, New Jersey 1947.[6]

Canada[8] is part of region 2 and as such is subject to the IARU band plan. Radio Amateurs of Canada offers the bandplan below as a recommendation for use by radio amateurs in that country but it does not have the force of law and should only be considered a suggestion or guideline.
