Can you get FNC?
Yes, and there are others too I think.

I have a ROKU as well. We just ditched our cable a couple of weeks ago. We bought our own modem so we would not be renting from Comcast, and upped our internet speed. I told the Comcast rep I didn’t want to haggle with them every six month over cable costs. I got the cable (105mpbs) at the regular price of $78.95. Son and wife will be moving in with us soon, so we’ll need the extra.
We downloaded the SlingTV app on Roku for 21.00 a month and we have Netflix. Sling not for everybody. It has about 14 stations, but it has stations that we watch regularly, and it’s live tv.
Fox News Channel has an app on Roku, and you can watch segments of programs - some the day after. We use Zahipedia to watch Fox News Channel live on the computer:

All of our tv viewing need are met. My husband is a fan of old movies and tv shows, and we both like home and garden/renovation shows.
