The Main Group of Tv stations is to the West.
For a indoor type antenna install a Terk HDTVi (not HDTVa) antenna in/at the North West facing window Up High in/at the window.
If a long continues length of coax is required to connect the HDTVi antenna that is in the North West facing window to the Tv and the long continues length of coax runs through the Apartment to do it.
