The multiswitch allows to mix VHF and UHF TV signals and SAT IF (950-2150 MHz, from four polarizations) and distribute them with one coaxial cable to four satellite receivers. For larger number of receivers there will be also needed cascadable multiswitches R70553, and - in big installations - the R70501 amplifiers. Multiswitch is powered with external power supply, e.g. R71465.
