In electronics, an antenna amplifier (also: aerial amplifier or booster) is a device that amplifies an antenna signal, usually into an output with the same impedance as the input impedance. Typically 75 ohm for coaxial cable and 300 ohm for twin-lead cable. An antenna amplifier boosts a radio signal considerably for devices that receive radio ...
A radio-frequency power amplifier (RF power amplifier) is a type of electronic amplifier that converts a low-power radio-frequency (RF) signal into a higher-power signal. [1] Typically, RF power amplifiers are used in the final stage of a radio transmitter , their output driving the antenna .
Remote electrical tilt is abbreviated as RET and it is part of the Antenna Interface Standards Group's open specification for the control interface of antenna devices. [2] Occasionally, mechanical and electrical tilt will be used together in order to create greater beam tilt in one direction than the other, mainly to accommodate unusual terrain.
A Zenith Space Command 600 remote control A box advertising a remote control system often referred to as "Space Command Tuning" The original television remote control was a wired version, released in 1950, that soon attracted complaints about an unsightly length of cable from the viewer's chair to the television receiver.
This remote control uses a two-wire circuit to control a base station. Current loop circuits are one possible way used to control radio base stations at distant sites. The two-way radio industry calls this type of remote control DC remote. This name comes from the need for DC circuit continuity between the control point and the radio base ...
In this case the feed system just consists of an impedance matching circuit (if needed) between the antenna and transmitter or receiver, which matches the impedance of the antenna to the radio. [3] In other cases the antenna is located separately from the transmitter or receiver, such as broadcast television antennas and satellite dishes ...
The RC-5 protocol was developed by Philips in the early 1980s as a semi-proprietary consumer IR remote control communication protocol for consumer electronics.It was subsequently adopted by most European manufacturers, as well as by many US manufacturers of specialty audio and video equipment.
Electronic programming guide interface in MythTV.. Electronic programming guides (EPGs) and interactive programming guides (IPGs) are menu-based systems that provide users of television, radio, and other media applications with continuously updated menus that display scheduling information for current and upcoming broadcast programming (most commonly, TV listings).
