The best way to get the coax from the antenna on the patio to the Tv in the apartment is the coax goes through a hole through the wall.

The Tv Must Channel Scan for the Digital Broadcast Tv Stations/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.
Can also try reception with the ANT751 antenna inside of the apartment with the ANT751 aimed through the glass patio doors.
