I use one of these DB4 Multi Directional HDTV Antenna. Search for it on Amazon. Just this weekend I unhooked my cable and had this antenna in the attic. I had RG6 coax run from the attic to the crawlspace. I ran this to my TV. Good results. I dropped cable Monday morning saving $100 month now. But you need a TV with a digital tuner. Otherwise you need some kind of box. I'm feeling real good right now about the savings. Time Warner raised their price by about 8% starting Jan 1st.
I want to use an OTA HD antenna...
but I don't know what brand to buy. Also, my CRT doesn't have a tuner, so I need a recommendation on that too.
