Satellite Dish

I have been asked to remove my satellite dish by the people who are buying my house. The dish is on a pole in my back yard.  I am just now cutting off my directv service so that means it will be the next billing cycle almost a month from now.  There are wires going into the dish.  Arent they live wires.  Wont I electrocute myself if I chop them off or try to undo them?  What to do???  The girl at directv told me the dish is mine but didnt know what to do about the wires.
