you can yes however if you pay for installation when you buy a freesat receiver, the shop will charge you £80. if you cant align a dish yourself but you put it up yourself it'l cost you £30-£40 for a local installer to align it for you (any more & their ripping you off). if you can drill a hole in a wall then you can put a satellite dish up, it aint hard

look in the yellow pages or on
http://www.yell.com for a local installer, dont use the shop where you got it from as £80 is day light robbery.
