MD-3004 and No.3000 Multi Switches are used to provide satellite signals of either RHCP or LHCP polarization from one dish at 4 OR 8 Locations. In addition, when required, they provide terrestrial VHF/UHF signals diplexed on the same coaxial cable. At the customer outlet, the satellite signals are separated from the VHF/UHF signals with a diplexer such as D-122 or D-400.
