Whip antenna is a single element antenna made up of a straight rod or flexible wire. As the name suggests, it makes a whip like sound when disturbed. The flexible wire is connected to the RF transmitter/receiver at bottom end. They are usually made up of interlocking metal tubes so that it can be folded back when not in use. They are used in hand-held radios, cordless phones, walkie-talkies, FM radios, boom boxes, and Wi-Fi enabled devices, and attached to vehicles as the antennas for car radios and two-way radios for wheeled vehicles and for aircraft.
