So I have Fios at my house, I would like to run another cable from the fios box on my house outside wall ( buried cable comes from pole to house)to my detached garage. Ideally this would be run overhead as I already have a metal cable run overhead from the house to the garage (75 feet) that the new fios wiring can be suspended from / attached to. The way it is now I have a splitter at the equipment box on the outside of my house and a coax type cable screws in to it then goes through my attic to my router for the house, I was wanting to connect another cable to empty spot on the the splitter and run a cable to my garage for internet out there, wth a separate router. Anyone know if this is feasable and if I can hire it done by an independent contractor, located in Dallas TX
