Antenna
A device collects and radiates electromagnetic waves. Includes a satellite dish and
broadband antenna.
DiSEqC
DiSEqC(Digital Satellite Equipment Control)system, it is a communication
bus between satellite receivers and peripheral equipment using the only
existing coaxial cable.
DVB
The Digital Video Broadcast group was created to establish a technical
framework for the introduction of digital video broadcasting systems.
LNB (low-noise block converter) or LNBF
An electronic unit mounted on the satellite dish. It receives signals reflected by the dish
and converts them to signals that can be used by the
digital satellite receiver.
GHz
The prefix Giga means milliard, and Hertz means cycles per second. Signals in the GHz
range are often called microwaves.
MHz
The prefix mega means million, and Hertz means cycles per second.
