Abstract
A dual LNB/TV antenna multi-switch allowing DC voltage provided by a satellite receiver to travel through the terrestrial antenna input without causing interference, distortion or lowering the signal strength of the satellite and terrestrial antenna pictures. By including an external DC block adapter with the invention, the multi-switch can be used with both amplified and non-amplified antennas and not require an external power injector.
Claims12
A dual LNB mini-dish system with an outdoor antenna comprising:
- a multi-switch comprising (a) at least two satellite signal ports, (b) at least one terrestrial antenna port, (c) a DC voltage path connected to said terrestrial antenna port allowing DC voltage to travel up to said terrestrial antenna port, and (d) at least one output port;
- a dual LNB mini-dish satellite antenna connected to said at least two satellite signal ports of said multi-switch and inputting a satellite signal into said multi-switch;
- a terrestrial TV antenna connected to said at least one terrestrial antenna port and inputting a terrestrial antenna signal into said multi-switch;
- at least one satellite receiver connected to said at least one output port of said multi-switch and capable of receiving a selected signal from said multi-switch,
- wherein said DC voltage path of said multi-switch enables a DC voltage signal from said satellite receiver to travel to said terrestrial TV antenna.
