Just brought a tv with freeview built in, I have a satelite for sky and an extra cable that is rg6 and a F connector. What do I need to do to be able to plug it into my tv? Can I plug this cable directly into my tv? Sorry noob here lol.
As above. You can't plug your satellite dish into your TV. The TV doesn't have a satellite tuner. The spare RG6 and f plug is probably a parallel feed from your Sky dish (newer ones have twin coax). You need to plug in the same coax you had plugged into your old TV. However if the aerial isn't UHF and/or you aren't in a Freeview HD area then you will only be able to tune Analogue TV (same as your old TV) and your Digital tuner won't be able to receive anything. Where are you located and what is you current TV antenna?
The Cookies and Cream with a chocloate flake version is Terrestrial / UHF / Land Based / freeview HD. You need a UHF / Long narrow type aerial for this.
The plain vanilla freeview comes via satellite (from the same satellite that Sky TV use). You need a satellite dish for this one.
TV's only have terrestrial tuners in them so they need to be connected to a UHF aerial, and you need to live in a freeview HD reception area.
Both types use RG6 cable to bring the signal to your TV. Normally you'd want one run of RG6 for the aerial and another separate run of RG6 to a sky box. Keeping them separate just simplifies the whole systems.
