Can I use the coaxial cable that is connected to my wifi router for my tv?

I have two coaxial cables in my house that I'd assume are connected to an antenna on my roof. One of them is red to connect to my wifi modem. If I plugged the other one into my tv, would I receive ota v channels? I'm not great with this technical stuff
Update: Didn't notice all the typos,
*used not red

*tv not v
