A low-noise block downconverter is the receiving device mounted on satellite dishes used for satellite TV reception, which collects the radio waves from the dish and converts them to a signal which is
A disassembled LNB. A waveguide carrying the microwave signal from the external dish antenna enters at the hole in the center, where two pins act as internal antennas (for two different polarizations). Here the microwave signal is coupled into microstrips on the LNB's circuit board, in order for the RF signal to be amplified and downconverted into lower frequencies, which are output at the two F connector sockets at the bottom.
