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.
A typical Ku band universal LNB designed for the European market can be switched between four modes (two frequency ranges and two polarisations) selected by signals from the receiver (supply voltage for polarisation and presence or absence of a 22 kHz tone for frequency range). This means that each receiver needs a separate feed and twin-tuner receivers (such as Sky+™ and Freesat+™) need two separate feeds. For small numbers of receivers a multi-output LNB is used and all the feeds are taken straight from the LNB but there is a limit to the number of outputs that can reasonably be placed on a LNB.
