2. Random wire antenna - Wikipedia

   en.wikipedia.org/wiki/Random_wire_antenna

   Often random wire antennas are also (inaccurately) referred to as long-wire antennas.There is no accepted minimum size, but actual long-wire antennas must be greater than at least a quarter-wavelength (⁠ 1 / 4 ⁠ λ) or perhaps greater than a half (⁠ 1 / 2 ⁠ λ) at the frequency the long wire antenna is used for, and even a half-wave may only be considered "long-ish" rather than "truly ...

3. List of RF connector types - Wikipedia

   en.wikipedia.org/wiki/List_of_RF_connector_types

   Belling-Lee connector, also called IEC 61169-2 connector, used throughout Europe and Australia, as well as parts of South-East Asia, for domestic television and FM radio antenna cabling; BNC connector (Bayonet Neill-Concelman). (IEC 61169-8 and IEC 61169-63) C-type connector (Concelman)

4. Antenna types - Wikipedia

   en.wikipedia.org/wiki/Antenna_types

   If used for transmitting, the resistor makes traveling-wave antennas inefficient, since the resistor absorbs any radio wave after the wave has made a single pass through the antenna wire, as opposed to a resonant antenna in which radio waves cycle back-and-forth several times, giving the signal multiple opportunities to radate.

5. Antenna (radio) - Wikipedia

   en.wikipedia.org/wiki/Antenna_(radio)

   This is the type of antenna used in most portable AM broadcast receivers (other than car radios): The standard AM antenna is a loop of wire wound around a ferrite rod (a "loopstick antenna"). The loop is resonated by a coupled tuning capacitor, which is configured to match the receiver's tuning, in order to keep the antenna resonant at the ...

6. Mast radiator - Wikipedia

   en.wikipedia.org/wiki/Mast_radiator

   Types of antenna often mounted on mast radiators are: fiberglass whip antennas for land mobile radio systems for taxi and delivery services, dish antennas for microwave relay links carrying commercial telecommunications and internet data, FM radio broadcasting antennas consisting of collinear bays of twisted dipole elements, and cellular base ...

7. Twin-lead - Wikipedia

   en.wikipedia.org/wiki/Twin-lead

   500–600 Ω open wire line or ladder line feeding a high wire antenna. The "ladder rung" spacers can be made out of any convenient insulating material – at present, usually short pieces cut from plastic plumbing pipe – formerly either long, thin ceramic insulators or dowel stubs of water-proofed wood were used.

8. Discone antenna - Wikipedia

   en.wikipedia.org/wiki/Discone_antenna

   The discone antenna has a useful frequency range of at least 10 to 1. [2] [3] When employed as a transmitting antenna, a properly constructed discone is just as efficient as an antenna designed for a more limited frequency range. The extra bandwidth comes from the controlled taper and large termination radius of the cone.

9. Cage aerial - Wikipedia

   en.wikipedia.org/wiki/Cage_aerial

   This antenna achieved transatlantic contacts on 1.5 MHz, at a power of 440 W. A cage antenna ( British cage aerial ) is a radio antenna where a conventional design has been augmented by replacing a single long conductor with several parallel wires, connected at their ends, and held in position by ring spacers or support struts mounted on a ...
