Using Plex with cable tv



I am currently using PLEX to stream my media, mostly movies and photos. I saw that there is an option to use OTA with the new feature of live TV. However in my country most of the channels are digital, so you need to have a decoder. What I want to know is if it's possible for me to connect the paid cable subscription I have to PLEX and watch it on every device. Currently my cable TV is being delivered via a coax cable that goes directly into my TV, which has a build in digital decoder.

I apologize if the question is stupid or I missed some information. Just to summarize I want to be able to watch/stream my coax tv subscription using Plex on different devices.
