An ionospheric heater, or an ionospheric HF pump facility, is a powerful radio wave transmitter with an array of antennas which is used for research of plasma turbulence, the ionosphere and upper atmosphere.
A Motorola connector (also called a Motorola antenna plug [citation needed] or a male DIN 41585 [1]) is a common coaxial cable RF connector used primarily in the automotive industry for connecting the coaxial feedline from the antenna to the radio receiver. It is also sometimes used for connecting scanner antennas to scanners.
Overhead console with programmable HomeLink buttons. The HomeLink Wireless Control System is a radio frequency (RF) transmitter integrated into some automobiles that can be programmed to activate devices such as garage door openers, RF-controlled lighting, gates and locks, including those with rolling codes.
The antenna may be enclosed inside the receiver's case, as with the ferrite loop antennas of AM radios and the flat inverted F antenna of cell phones; attached to the outside of the receiver, as with whip antennas used on FM radios, or mounted separately and connected to the receiver by a cable, as with rooftop television antennas and satellite ...
The "Kerbango Internet Radio" was a product, never released, that would allow users to listen to Internet radio without a computer.[1]An Internet radio device, also called network music player is a hardware device that is capable of receiving and playing streamed media from either Internet radio stations or a home network.
Commercial FM broadcasting transmitter at radio station WDET-FM, Wayne State University, Detroit, US.It broadcasts at 101.9 MHz with a radiated power of 48 kW.. In electronics and telecommunications, a radio transmitter or just transmitter (often abbreviated as XMTR or TX in technical documents) is an electronic device which produces radio waves with an antenna with the purpose of signal ...
A mast radiator or mast antenna is a radio tower or mast in which the whole structure is an antenna. Mast antennas are the transmitting antennas typical for long or medium wave broadcasting. Structurally, the only difference is that some mast radiators require the mast base to be insulated from the ground.
Radiative coupling or electromagnetic coupling occurs when source and victim are separated by a large distance, typically more than a wavelength. Source and victim act as radio antennas: the source emits or radiates an electromagnetic wave which propagates across the space in between and is picked up or received by the victim.
