ABSTRACT:
A television signal distribution network includes respective distributor cables for signals from respective satellite antennas, one of such cables also being coupled to a terrestrial signal source and serving as a dual distribution cable for both satellite and terrestrial signals. A switching unit permits each user terminal to be selectively connected to any of the distributor cables for reception of a selected satellite signal. The user terminals are also all coupled to the dual cable via a filter which only passes the terrestrial signal band, whereby the terrestrial signal is distributed to all terminals from only a single cable, independently of the setting of the switching unit. Another of the distributor cables also serves as a return cable for upstream signals from the user terminals. The return path includes a filter which only passes an upstream frequency band below that of the terrestrial and satellite signals.
