IRS (integrated reception systems) enable terrestrial UHF and satellite IF signals plus FM/DAB to be combined into one cable feed. The signal is then split at the TV point using combination faceplate outlets. They are used in communal reception systems and in many of the home system we install.
It is possible to use a switch that can accept multiple satellite feeds to send via a single cable that uses disecq commands to switch between inputs.
Fibre optic cable system allow for long distances between dish and receiver points and can be used on very large developements with little or no loss.
