The extension also had inductors at the far end, such that each part of the antenna had inductors at its ends. In 1925, the two parts of the antenna were split, each now operating separately (the original as callsign MUU, the 1924 antenna as GLC), a new feed taken up the mountain from the western transmitter buildings to the site of the double ATI.
The RCA connector [3] is a type of electrical connector commonly used to carry audio and video signals. The name RCA derives from the company Radio Corporation of America, which introduced the design in the 1930s. [4] The connector’s male plug and female jack are called RCA plug and RCA jack. It is also called RCA phono connector [5] or phono ...
RCA Plugs for composite video (yellow) and stereo audio (white and red) RCA connectors , also known as phono connectors or phono plugs , are used for analog or digital audio or analog video. These were first used inside pre–World War II radio-phonographs to connect the turntable pickup to the radio chassis.
RCA ownership of RKO stock expanded from about one quarter in 1930 to about 61% in 1932. [35] RKO encountered severe financial problems, going into receivership from early 1933 until 1940. RCA sold its holdings in the studio to raise funds for its basic operations. [citation needed]
An antenna rotator (or antenna rotor) is a device used to change the orientation, within the horizontal plane, of a directional antenna. Most antenna rotators have two parts, the rotator unit and the controller. The controller is normally placed near the equipment which the antenna is connected to, while the rotator is mounted on the antenna ...
Analog or digital data such as transmitter power, temperature, VSWR, voltage, modulation level, and other status information are returned so that broadcast engineering staff can correct any problems as soon as possible. These data may be attended to by an automated transmission system.
NMO mount connector (new Motorola mount), removable mobile antenna connector uses a 3 ⁄ 4 inch (19 mm) mounting hole and has a large base with a 1 1/8" – 18 tpi thread for attaching the antenna. SC connector, screw version of C connector [not to be confused with the fiber optic connector of the same name]
An antenna tuner, a matchbox, transmatch, antenna tuning unit (ATU), antenna coupler, or feedline coupler is a device connected between a radio transmitter or receiver and its antenna to improve power transfer between them by matching the impedance of the radio to the antenna's feedline. Antenna tuners are particularly important for use with ...
