A flexible vertical rod antenna, used chiefly on vehicles. Also known as fishpole antenna.

Whip Antenna

 

an antenna in the form of an asymmetrical dipole made from a rigid metal rod or a large number of metal coils strung on a flexible steel line. The rigid rod may be solid or may consist of several coupled sections. In the USSR, a whip antenna made from metal coils strung on a steel line is known as a Kulikov antenna. Whip antennas made from a shaped metallic strip, a braided wire, or a metal-coated dielectric rod are used less often.

The radiation pattern of a whip antenna in the horizontal plane is circular (see Figure 2 in ANTENNA). Therefore, whip antennas are especially suited for communication between ground-based objects whose relative position changes in time, for example, between mobile radio sets in motor vehicles or tanks.
