Do you wish to continue using your existing Sky box as well as a new Freesat box? If so, then yes, you need an additional cable - you will also need a new widget to sit on the arm attached to your dish. The widget is called an LNB (low-noise blocker) but to run two set-top boxes you will need a 'dual LNB' that is capable of feeding two different boxes simultaneously.

Every satellite set-top-box requires its own connection to the dish, as the box needs to send tuning instructions to the LNB attached to the dish as well as receiving signals from it.
