Thanks for your quick response. I bought this indoor antenna.

But when I put it next to TV, the image is not clear and I get a lot of interference and broken images. So I put the same antenna in the backyard and use a cable from there to connect to TV, the image is a lot better. That was the reason I was thinking may be I need a multi-directional outdoor antenna.
This is my first experimentation with antennas so I do not have any clue. Please let me know your thoughts. Also I have a old Sony trinitron flat screen TV and looking to get OTA on that. Do you also have any suggestions for digital tuners for this. And also can I use the same antenna for both the TVs?
Thanks and I really appreciate your help.
