The benefits of cable over satellite is mainly the contract. With cable you are not forced to sign a 1 or two year contract to be able to watch tv. You will not have wires hanging all around your home with cable which can be annoying. Another thing is you can watch the same cable in many different rooms without having to rent additional cable boxes for other tvs. For cable television, you need only the cable box to connect the coaxial cable from the wall to your television. With satellite television, you need the receiver as well as the dish. Cable television will generally continue to be viewable during inclement weather, while satellite television will often go out during storms. With satellite television, you may periodically need to replace or reset the dish, as it can be knocked from its position or damaged.
