In radio communication, an omnidirectional antenna is a class of antenna which radiates radio wave power uniformly in all directions in one plane, with the radiated power decreasing with elevation angle above or below the plane, dropping to zero on the antenna's axis.
 This radiation pattern is often described as "doughnut shaped".
 Note that this is different from an isotropic antenna, which radiates equal power in "all" directions and has a "spherical" radiation pattern.
 Omnidirectional antennas oriented vertically are widely used for nondirectional antennas on the surface of the Earth because they radiate equally in all horizontal directions, while the power radiated drops off with elevation angle so little radio energy is aimed into the sky or down toward the earth and wasted.
 Omnidirectional antennas are widely used for radio broadcasting antennas, and in mobile devices that use radio such as cell phones, FM radios, walkie-talkies, wireless computer networks, cordless phones, GPS as well as for base stations that communicate with mobile radios, such as police and taxi dispatchers and aircraft communications.
The Royal Commission on Radio Broadcasting, otherwise known as the Aird Commission, was chaired by John Aird and examined Canada's broadcasting industry.
 The report released its findings in 1929 when it concluded that Canada was in need of a publicly funded radio broadcast system.
 The Aird Report eventually resulted in the creation of the Canadian Radio Broadcasting Commission, the forerunner of the CBC.
A radio personality (American English) or radio presenter (British English), commonly referred to as a "disc jockey" or "DJ" for short, is a person who has an on-air position in radio broadcasting.
 A radio personality that hosts a radio show is also known as a radio host, and in India and Pakistan as a radio jockey.
 Radio personalities who introduce and play individual selections of recorded music are known as disc jockeys.
 The term has evolved to also describe a person who mixes a continuous flow of recorded music in real time.
 Broadcast radio personalities may include talk radio hosts, AM/FM radio show hosts, and satellite radio program hosts.
 Notable radio personalities include pop music radio hosts Martin Block, Alan Freed, Dick Clark, Delilah Luke, Ameen Sayani, Wolfman Jack, and Casey Kasem, shock jocks such as Don Imus and Howard Stern, as well as sports talk hosts such as Mike Francesa and political talk hosts such as Rush Limbaugh.
