Movign to new house soon. Want to purchase a Freeview box. There will be aerial lead to loft (connections to TV aerial points). I notice you can get loft aerials suitable for digital reception from Argos/Index for what seems to be a reasonable £40. Question is, do I need to get a professional fitter out or can I fit them myself (I'm handy with DIY). Note that the description in Index catalogue says, "including full intructions and fixing kit".
