A Terk HDTVi Non amplified indoor type antenna will be a excellent antenna for a survey of indoor reception and outside reception. Here is how to aim indoor type antennas ,

I suggest start with the HDTVi in a second story window that you can look out and see to the north east and , Scan for the digital broadcast tv channels , that way a larger number of channels will be in the tuner , making it easyer to select channels and see how well the tv station/channel is being received at different locations. Also at any location you can do a new scan and see what is received at that location. Get a Looong length of coax and coax couplers to connect it all to geather.
