the antenna would connect to the tv itself and then you need to run the channel set-up from the tv menu. it will scan the system and mark whatever channels it finds. as audiophile pointed out, you can then output the sound from the tv to a home theater if you have one.
*** note that the tv's channel finder may not get them all. if you are missing channels you may have to manually add them through the same menu. should be a manual edit choice where you can add channels it may have missed. my tv missed about 5 channels from the antenna when i ran it. but they added easily and come in strong so no idea why they tend to miss random channels.
