 | | The cable TV headend will normally have several large, television receive-only satellite television dishes for reception of cable/satellite TV networks such as ESPN, CNN, or HBO (examples); a dedicated, non-movable dish is required for each satellite that the cable TV utility wishes to receive cable channels off of for distribution over its system. |
 | | For reception of signals off several adjacent satellites, a larger non-parabolic multi-satellite dish (such as the Torus) that can see up to 3 satellites is often used. |
 | | Once received, cable television signals are often pre-amplified and then mixed into the cable system's channel numbering scheme using a frequency multiplexer. |
