The following is a Teleview recommendation for broadcast Tv reception.
The Main group of Digital Tv transmitters is to the South with a few a little more to the south east.
Install a Trek HDTVi (not the HDTVa) indoor antenna in a preferably south facing window for best reception , also so can put the HDTVi antenna in the south east window.
A long length of coax can go from the antenna to the Tv.
Aim the HDTVi antenna at about 181 degree magnetic compass.
Here is how to aim indoor type antennas.
