Intermittent and pixelated picture at times on my Digital HDTV?

Can anyone tell me why my TV has a pixelated picture during random times of the day? I have an outdoor antenna but no preamp. Should I buy a preamp? Which one should I get?

Thanks in advance.

There are SO many reasons why that would occur, we need a little more information from you, before we can say much.

Go to...
and fill out the information, Then, copy the link in bold type above your chart into your next post here. It also would be nice if you knew what kind of Antenna you have. If not, can you take a picture of it for us ?
That'll be a start.

Have a good Day ! :)

Antenna type and where your stations are in relation to you and the antenna are major factors. If you have a noisy signal to begin with the amp will just amplifiy the noise.
