If the building has , metal backed insulation , metal roof , solar panels , concrete walls , concrete blocks , cinder blocks , bricks from ground to roof , big rocks for walls , reception will be reduced or blocked.
As always trees and tree leaves do a real fine job of reducing or blocking Tv reception and so do buildings and other obstructions.
The Tv Must Channel Scan for Digital Broadcast Tv Channels , sometimes named the 'Air Channels' or 'Antenna Channels' in the Tv setup menu because the Tv transmissions travel through the air from the transmitting antenna to the receiving antenna.
DO NOT channel scan for cable tv channels.
If there is reception problem , then put the HDTVi antenna in a north window , and connect to the Tv with a long coax.
