These tables detail the frequencies used in European cable networks. Cable networks use frequencies which are used by different users over-the-air, like the military, police radio, etc. Because of the late introduction of cable television in Europe, older television sets generally could not receive the special cable-only channels, so some countries (like Germany) still have the rule that the public TV stations must be located either in Band I or Band III. The Hyperband was allocated later than the other cable-only channels, so television sets produced in the late 80s and early 90s may lack this band.
