How can I connect both from the wall cable and antenna wire to my HD TV My cable provider offers a low cost 10-12 dollars a month plan I dont want to rent cable box or use a manual switch?

The antennan wire on your HDTV will connect to the back of the television set, if it is antenna compatible. The wall cable will go to the audio in location where you connect the coaxial cable. A digital antenna converter box will be needed to make the television work without a true digital signal coming into the home.
