Use of TV antenna for Tuner

I recently moved into a house where the previous owner had an older style TV antenna hooked up to a television. It's a huge aluminum antenna attached to the top of the roof. I believe it is a round 75 ohm wire, the one with the piece of wire in the center housed in a round threaded terminal. The wire is still attached to the antenna and was run through the wall and ends conveniently right behind my rig in the living room. I was thinking of getting a tuner. Can I use this antenna and hook up the wire to the 75 ohm connector on the back of the tuner? Will it be able to be used with both digital and analogue tuners? What will I need to do to get this antenna to work?

Thanks for any help
