Larger versions mounted on roofs, balconies and radio masts are used as base station antennas for amateur radio and police, fire, ambulance, taxi, and other vehicle dispatchers.įiberglass whip for 2m and 70cm amateur radio bands, with ground plane radials They are widely used as the antennas for hand-held radios, cordless phones, walkie-talkies, FM radios, boom boxes, and Wi-Fi enabled devices, and are attached to vehicles as the antennas for car radios and two-way radios for wheeled vehicles and for aircraft. Whips are the most common type of monopole antenna, and are used in the higher frequency HF, VHF and UHF radio bands. The most common type is the quarter-wave whip, which is approximately 1 / 4 wavelength long, but they can be either longer or shorter by design, varying from compact electrically short antennas 1 / 10 wavelength long, up to 5 / 8 wavelength to improve directivity. The ideal length of the whip antenna is determined by the wavelength of the radio waves it is used with. 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 (35 feet) long. 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. The antenna is designed to be flexible so that it does not break easily, and the name is derived from the whip-like motion that it exhibits when disturbed. A whip antenna is a form of monopole antenna. The bottom end of the whip is connected to the radio receiver or transmitter. A whip antenna is an antenna consisting of a straight flexible wire or rod.
