Comprises two universal LNBs fixed together at a small angle in a single housing. Only one "F" connector is used. A single coaxial cable connects to the Digital (or Digital + Analogue) receiver which must be able to use DisEqC signalling to select which LNB is to be used. Normally used on an 80cm dish to receive Astra at 19.2’E and Hotbird at 13’E (but not simultaneously) but versions are also available for receiving other combinations of satellites too with Hotbird and Eurobird now proving popular due to many adult channel packages using both satellites for transmissions.
This type of LNB has a single output and the actual satellite signal is selected by the receiver which sends a DisEqC (22kHz) pulsed tone up the LNB cable. So only one satellite transmission can be viewed at a time. This is in contrast with dish systems that have two or more separate LNBs where, with two receivers, both satellite transmissions can be viewed or recorded simultaneously. Not compatible with a Sky Digibox. Not suitable for fitting to a Sky minidish.
