Tower Guy is correct. CBS, ABC, and NBC are very weak and blocked by terrain.

I suggest that you connect the second antenna to a Mediasonic HW-150 converter box with its output connected to the HDMI input the TV.

The HW-150 will allow you to add a channel after a scan using the Manual Search window in the menu. This keeps you from having to rescan over and over again when hunting for a missing channel.
