rooftop antennae for tuner and TV

Actually, it is the other way around. Get a very good TV antenna and you will also get very good FM. The FM band is between TV channels 6 and 7, so the TV VHF will work great.

I have a large Winegard TV antenna in my roof/attic crawl space. I patched it into the cable TV junction (which I don't use for cable), and with the help of a antenna preamp to boost the signal, I get TV in every room just by plugging the TV into the cable wall plug.

In the 2 rooms with the audio systems, the tuner is just plugged into the cable wall plug as well. One of those rooms has a small TV, so I just use a splitter.

Generally, an antenna designed for FM only will offer limited usefulness for TV, especially UHF. The FM band exists within the TV bands (I think FM frequencies are between channels 6 and 7 -- or is it 7 and 8? -- of the TV frequencies). So, while a TV antenna should be able to pull in FM signals, an antenna designed for FM frequencies would probably not have the spectrum bandwidth for all TV signals.

this is probably a dumb question. how do you get channel 6 , 7 or 8 on the tv antenna to work on you fm tuner. there is no channel to select. I have radio shack rooftop TV/antenna. it gets great reception for tv but it doesn't do anything for my fm tuner.am i doing something wrong ?
