2. Shortwave radio receiver - Wikipedia

   en.wikipedia.org/wiki/Shortwave_radio_receiver

   Modern shortwave radio receivers are relatively inexpensive and easily accessible, and many hobbyists use portable "world band" receivers and built-in telescopic antennas. Serious hobbyists may use communications receivers and outdoor antenna located away from electrical noise sources, such as a dipole made from wire and insulators.

3. Whip antenna - Wikipedia

   en.wikipedia.org/wiki/Whip_antenna

   A whip antenna is an antenna consisting of a straight flexible wire or rod. The bottom end of the whip is connected to the radio receiver or transmitter. A whip antenna is a form of monopole antenna. 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 ...

4. Antenna types - Wikipedia

   en.wikipedia.org/wiki/Antenna_types

   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 ...

5. Shortwave listening - Wikipedia

   A Sangean ATS-909 world band receiver. Shortwave listening, or SWLing, is the hobby of listening to shortwave radio broadcasts located on frequencies between 1700 kHz and 30 MHz (30 000 kHz). [1]

6. 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 ...

7. TV and FM DX - Wikipedia

   en.wikipedia.org/wiki/TV_and_FM_DX

   For example, reception of satellite signals requires sensitive receiving systems and large outdoor antenna systems. However, unlike terrestrial TV DX, satellite UHF TV reception is far easier to predict. The geosynchronous satellite at 22,375 miles (36,009 km) height is a line of sight reception source. If the satellite is above the horizon, it ...

9. Rubber ducky antenna - Wikipedia

   en.wikipedia.org/wiki/Rubber_ducky_antenna

   The rubber ducky antenna (or rubber duck aerial) is an electrically short monopole antenna, invented by Richard B. Johnson, that functions somewhat like a base-loaded whip antenna. It consists of a springy wire in the shape of a narrow helix , sealed in a rubber or plastic jacket to protect the antenna. [ 1 ]
