The ideal LNB, effectively a perfect amplifier, would have a noise figure of 0 dB and would not add any noise to the signal. Every LNB introduces some noise but clever design techniques, expensive high-performance low-noise components such as HEMTs and even individual tweaking of the LNB after manufacture, can reduce some of the noise ...
Monoblock (or monobloc) low-noise block downconverters are a special type of LNBs representing a single device that contains several (typically 2–4) LNB units and a Digital Satellite Equipment Control (DiSEqC) switch. The latter allows the recipient to receive signals from several neighboring satellites each communicating different channels ...
Linux, MacOS and Windows QSO logger for Emacs with a customizable dynamic form for rapid data entry into an ADIF file. Suitable for general logging or contesting, it can be customized to use almost any combination of fields in the ADIF 3.1.4 specification.
Block diagram of a superheterodyne receiver. The RF front end consists of the components on the left colored red. In a radio receiver circuit, the RF front end, short for radio frequency front end, is a generic term for all the circuitry between a receiver's antenna input up to and including the mixer stage. [1]
It protects the receiver front-end element (the low-noise block downconverter, LNB) from burn-out by the power of the output signal generated by the block up converter (BUC). The BUC is also connected to the feed horn through a wave guide port of the OMT junction device.
Plex, a cross-platform and closed source software media player and entertainment hub for digital media, available for macOS, Microsoft Windows, Linux, as well as mobile clients for iOS (including Apple TV (2nd generation) onwards), Android, Windows Phone, and many devices such as Xbox. Supports on-the-fly transcoding of video and music.
In the box at the focus of the dish, called a low-noise block downconverter (LNB), each block of frequencies is converted to the IF range of 950–2150 MHz by two fixed frequency local oscillators at 9.75 and 10.6 GHz. One of the two blocks is selected by a control signal from the set top box inside, which switches on one of the local oscillators.
