Whip antenna

A whip antenna is an antenna consisting of a straight flexible wire or rod. The bottom end of the whip is connected to the radio receiver or transmitter. A whip antenna is a form of monopole antenna.

The antenna is designed to be flexible so that it does not break easily.
Whip antennas for portable radios are often made of a series of interlocking telescoping metal tubes, so they can be retracted when not in use.
Longer whips, made for mounting on vehicles and structures, are made of a flexible fiberglass rod around a wire core and can be up to 11 m long.
