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 ...
Digital television adapter. A digital television adapter ( DTA ), commonly known as a converter box or decoder box, is a television tuner that receives a digital television (DTV) transmission, and converts the digital signal into an analog signal that can be received and displayed on an analog television set. Some also have an HDMI output since ...
The F connector (also F-type connector) is a coaxial RF connector commonly used for "over the air" terrestrial television, cable television and universally for satellite television and cable modems, usually with RG-6/U cable or with RG-59/U cable . The F connector was invented by Eric E. Winston in the early 1950s while working for Jerrold ...
The FME female is designed to be low diameter to allow cables it has been installed on to be snaked through the often tight access holes or spaces of a vehicle to the desired equipment location(s) where an FME male adapter to the required equipment connector series is fitted to the female cable connector. The thread is 8mm*0.75mm pitch, and the ...
RF connectors ( radio frequency signals). Generally use coaxial cable types such as RG-6 and RG-59 (except for twin-lead). Belling-Lee/IEC 169-2 connector. TV aerial plug (a.k.a. antenna plug) Television antenna connection for most video devices outside North America.
The TNCA connector is a variant of the TNC connector specified in MIL-STD-348 [ 1] designed to provide an air gap in the dielectric region between the male and female connectors. The female TNCA connector is nearly identically to the standard TNC female connector, while the male TNCA connector provides the air cavity differentiating it from a ...
Twin lead (in the specific sense of ribbon cable) is a form of parallel wire balanced transmission line. The separation between the two wires in twin-lead is small compared to the wavelength of the radio frequency (RF) signal carried on the wire. [ 2](p 24βΈ—1) The RF current in one wire is equal in magnitude and opposite in direction to the RF ...
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 ...
