2. Whip antenna - Wikipedia

   en.wikipedia.org/wiki/Whip_antenna

   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 (35 feet) long. The length of a whip antenna is determined by ...

   However a few types of linear antennas are specifically made too small to resonate – short whip antennas, and unplanned random wire antennas, for example. Loop antennas ("magnetic" antennas) [ b ] Loops are ring-like antennas made out of segments of wire or metal tubing bent into a circle or polygon – any regular or irregular two ...

   Whip-A-Way folding antenna The Whip-a-way is a seven-section, tubular, folding whip antenna. A plastic-covered cable (or braided plastic cord) under spring tension is threaded through the sections to keep them together when assembled for operation and prevent their separation or loss when disassembled.

6. Citizens band radio - Wikipedia

   Typical center-loaded mobile CB antenna. Note the loading coil, which shortens the antenna's overall length. 27 MHz is a relatively long wavelength for mobile communications, and the choice of antenna has a considerable impact on the performance of a CB radio. A common mobile antenna is a quarter-wave vertical whip.

   The antenna may not be more than 20 feet (6.1 m) above the highest point of the structure it is mounted to, or the highest point of the antenna must not be more than 60 feet (18.3 m) above the ground (47 CFR 95.408(c)) if installed in a fixed location. [4] CB radios must include AM or SSB modulation and may include frequency modulation. [5]
