Used for elevated base station antennas for land mobile radio systems such as police, ambulance, and taxi dispatchers. Mast radiator A radio tower in which the tower structure itself serves as the antenna. Common form of transmitting antenna for AM radio stations and other MF and LF transmitters.
Omnidirectional antenna unless otherwise specified. A comma after the power indicates sunset. Whatever is after the comma is the night-time authorization, to avoid interfering with other, higher priority stations. Another comma indicates if it's a directional antenna system. DA means the station uses a directional antenna system.
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 ...
Ferrite loopstick antenna from an AM radio having two windings, one for long wave and one for medium wave (AM broadcast) reception. About 10 cm (4 inches) long. Ferrite antennas are usually enclosed inside the radio receiver. Ferrite loop antennas are made by winding fine wire around a ferrite rod. They are almost universally used in AM ...
Mast radiators make good ground wave antennas, and are the main type of transmitting antennas used by AM radio stations, as well as other radio services in the MF and LF bands. They also can radiate enough power at higher elevation angles for skywave (skip) radio transmission. Most radio stations use single masts.
In large urban centers, AM radio signals can be severely disrupted by metal structures and tall buildings. As a result, AM radio tends to do best in areas where FM frequencies are in short supply, or in thinly populated or mountainous areas where FM coverage is poor. Great care must be taken to avoid mutual interference between stations ...
Best Overall: Channel Master Ultra Mini Antenna Amplifier. Best Value: Antop TV Antenna Amplifier. Most Versatile: The Cimple Co TV Antenna Amplifier. Easiest Setup: Winegard LNA-100 Boost 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 ...
