Do i need a tv aerial if i have a sky dish

[Trish+H]

I want to move my TV to the other side of the room but the aerial is static and doesn't move and there isn't another one in the room.

Do I need it if I have a sky dish or does that provide everything?

The sky aerial is long enough to move so no problem there.

I do stream films etc on Netflix and Amazon prime, I also have a Firestick.

I also pay extra for HD with Sky, will I still get it without a terrestrial aerial?

A Sky Q television box has no aerial input, so does nothing with it at all.

Your television set, however, may be using the aerial for Freeview (digital terrestrial) reception.
