your tv antenna should have nothing to do with any internet connection you did not tell us what kind of internet your using are you using a cable modem on the park cable? then you would need to pull the tv antenna power switch plate from the wall and find the cable from the exterior cable connection disconnect it and connect it to a proper Cable Modem splitter like this
Cable Modem & MOCA Premium Coaxial 2-way Splitter then a cable from one of the splitter outputs goes back to where you removed the external cable from and one goes directly to the cable modem.
