2. Whip antenna - Wikipedia

   en.wikipedia.org/wiki/Whip_antenna

   The length of a whip antenna is determined by the wavelength of the radio waves it is used with. Their length varies from compact electrically short antennas ⁠ 1 / 10 ⁠ wavelength long, up to ⁠ 5 / 8 ⁠ wavelength to improve directivity. The most common type is the quarter-wave whip, which is approximately ⁠ 1 / 4 ⁠ wavelength long.

4. Antenna types - Wikipedia

   en.wikipedia.org/wiki/Antenna_types

   A whip antenna with several rods extending horizontally from base of the whip in a star-shaped pattern, similar to an upside-down radiate crown, that form the artificial, elevated ground plane that gives the antenna its name. The ground plane rods attach to the ground wire of the feedline, the other wire feeds the whip.

5. Television antenna - Wikipedia

   en.wikipedia.org/wiki/Television_antenna

   A 'whip' antenna at the side of a Casio portable TV. Some portable televisions use a whip antenna. [6] This consists of a single telescoping rod about a meter (3.3 feet) long attached to the television, which can be retracted when not in use. It functions as a quarter-wave monopole antenna.

6. Counterpoise (ground system) - Wikipedia

   en.wikipedia.org/wiki/Counterpoise_(ground_system)

   Inverted-L antenna with counterpoise, in a powerful amateur radio station, Colorado, 1920. The counterpoise is the lower grid of horizontal wires, suspended below the antenna. The largest use of counterpoises is in transmitters on the low frequency (LF) and very low frequency (VLF) bands, as they are very sensitive to ground resistance. [2]

7. Collinear antenna array - Wikipedia

   en.wikipedia.org/wiki/Collinear_antenna_array

   Collinear dipole array on repeater for radio station JOHG-FM on Mt. Shibisan, Kagoshima, Japan. In telecommunications, a collinear antenna array (sometimes spelled colinear antenna array) is an array of dipole or quarter-wave antennas mounted in such a manner that the corresponding elements of each antenna are parallel and collinear; that is, they are located along a common axis.

8. Base transceiver station - Wikipedia

   en.wikipedia.org/wiki/Base_transceiver_station

   A base transceiver station (BTS) or a baseband unit [1] (BBU) is a piece of equipment that facilitates wireless communication between user equipment (UE) and a network. UEs are devices like mobile phones (handsets), WLL phones, computers with wireless Internet connectivity, or antennas mounted on buildings or telecommunication towers.

9. Whip-a-way - Wikipedia

   en.wikipedia.org/wiki/Whip-a-way

   An antenna top cap installed on the tip of the antenna provides protection for personnel. The construction is the same as is used for sectional fishing poles. The base has a male 3/8-24 thread which is the same as is used on most ham radio and CB antennas. The antenna was 9 feet long when fully assembled.
