Making Addon for Local Channels

New to Kodi I hope I am posting this in correct place. I just bought 6 Fire Tv Sticks 2 days ago and loaded Kodi and put a kripton build on it. Problem is I can not seem to find any plugin that has local St louis stations Fox CBS NBC to have local news. I know I can put HD antenna on ea of the 6 tvs I am thinking it may be better to create the streams and make a addon. I can not seem to find any info on how to create the streams. Hoping someone can point me in the correct direction.

I am thinking since I have tons of computers a Desktop with TV tuner and HD antenna To stream the channels (run what ever streaming program in 4 instances Fox Abc NBC CBS) Thinking the stream’s could be put in file on dropbox then making the addon for Kodi set to pull the links from dropbox.

I am not sure that would be possible just what I was kicking around as starting point.

Any how nice to meet you all any how to’s or info is greatly appreciated.

My set up is 6x Fire tv stick Kodi 17 Spinz tv Furry Playstation vue sub and spinz pro sub. Playstation vue does not have local live they are ondemand in my area and all ones in build for kodi work but they are NY broad cast or Denver.
