Antenna gain-to-noise-temperature ( G/T) is a figure of merit in the characterization of antenna performance, where G is the antenna gain in decibels at the receive frequency, and T is the equivalent noise temperature of the receiving system in kelvins. The receiving system noise temperature is the summation of the antenna noise temperature and ...
Noise temperature (antenna) In radio frequency (RF) applications such as radio, radar and telecommunications, noise temperature of an antenna is a measure of the noise power density contributed by the antenna to the overall RF receiver system. It is defined as "the temperature of a resistor having an available thermal noise power per unit ...
A television antenna, also called a television aerial (in British English ), is an antenna specifically designed for use with a television receiver (TV) to receive terrestrial over-the-air (OTA) broadcast television signals from a television station. Terrestrial television is broadcast on frequencies from about 47 to 250 MHz in the very high ...
Antenna amplifier for broadcasting service (here: TV broadcasting and FM souns broadcasting. 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 ...
The weight of the Terrier booster system is 2,207 pounds (1,001 kg). [4] The Oriole stage is 22 inches (560 mm) in diameter and 155 inches (3,900 mm) long. It is powered by GEM-22 Graphite-Epoxy Motor. [5] There is a 14-inch (360 mm) interstage adapter between the Terrier and Oriole systems, which allows for drag separation following Terrier ...
e. 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 ...
A booster engine is used to start a heavy train or maintain low speed under demanding conditions. Rated at about 300–500 horsepower (220–370 kW) at speeds from 10 to 35 mph (16–56 km/h), it can be cut in while moving at speeds under 12–22 mph (19–35 km/h) and is semi-automatically cut out via the engineer notching back the reverse ...
The following is a list of programs that are and will be broadcast on Antenna TV, a general entertainment network owned by the Tribune Broadcasting subsidiary of the Tribune Company, which is designed for digital subchannels of over-the-air broadcast stations in the United States and was launched on January 1, 2011.
