a Multiswitch with 16 outputs, the four cables from the Quattro-LNB enter on the left. A multiswitch is a device used with a dual or quattro LNB to distribute satellite TV signals to multiple (usually more than four) receivers from a single dish and LNB.
The Pan-American television frequencies are different for terrestrial and cable television systems. Terrestrial television channels are divided into two bands: the VHF band which comprises channels 2 through 13 and occupies frequencies between 54 and 216 MHz, and the UHF band, which comprises channels 14 through 36 and occupies frequencies between 470 and 608 MHz.
Channel A video carrier is the same as Channel E2 audio carrier and thus it used to be common that the audio from a distant TV station on channel E2 received via Sporadic E interferes with Channel A video and vice versa. Channel C audio carrier's frequency falls into the FM band in Europe, and is also identical to American A6 channel audio.

Analog satellite television and terrestrial analog microwave relay communications rely on subcarriers transmitted with the video carrier on a satellite transponder or microwave channel for the audio channels of a video feed. There are usually at frequencies of 5.8, 6.2, or 6.8 MHz (the video carrier usually resides below 5 MHz on a satellite ...
Uplink facilities transmit the signal to the satellite over a narrow beam of microwaves, typically in the C-band frequency range due to its resistance to rain fade. [20] Uplink satellite dishes are very large, often as much as 9 to 12 metres (30 to 40 feet) in diameter [ 20 ] to achieve accurate aiming and increased signal strength at the ...
