Trying to connect my dp311 direct tv box to my new 49” 4K uhd lg

Having trouble with opposite style hookups from my sat.box to my tv

My suggestion would be to get a new box with HDMI. The old one is not HD and the picture will not be good.
Your new TV likely has a shared component - composite video input. Check the owners manual on how to configure it for composite and how to connect the DTV box.
