Indoor antenna advice?

[lnx64]

Since getting this TV from my grandfather and restoring back to full working condition, I am saddened that I get ONE channel.. Just one channel, and the garbage on it is pretty sad. I need something better than this, but my budget is limited. aka, basically nothing more than $10, so I got this 7 dollar antenna at Best Buy, and still only got one channel.. And barely.

This just isn't entertainment:

Soi need advice, what kind of antenna should I get indoors that works with ATSC broadcasts? Amplified even? This TV has an ATSC tuner built in, and has a decent standard def picture on it, but I'd like to pull in something more than just WMOR. Maybe ABC, CBS, NBC, the regulars would be nice.
