A whip antenna is an antenna consisting of a single straight flexible wire or rod, often mounted above some type of conducting surface called a ground plane. The bottom end of the whip is connected to the radio receiver or transmitter. They are designed to be flexible so that they won't break off, and the name is derived from their whip-like motion when disturbed. Often whip antennas for portable radios are made of a series of interlocking telescoping metal tubes, so they can be retracted when not in use. They are the most common type of monopole antenna. These antennas are widely used for hand-held radios such as cell phones, cordless phones, walkie-talkies, FM radios, boom boxes, Wifi enabled devices, and GPS receivers, and also attached to vehicles as the antennas for car radios and two way radios for police, fire and aircraft.

Famous quotes containing the word whip:
“I told them I’m not going to let Vietnam go the way of China. I told them to go back and tell those generals in Saigon that Lyndon Johnson intends to stand by our word, but by God, I want something for my money. I want ‘em to get off their butts and get out in those jungles and whip hell out of some Communists. And then I want ‘em to leave me alone, because I’ve got some bigger things to do right here at home.”
—Lyndon Baines Johnson (1908–1973)
