How do I get a better over the air HDTV Signal? - best antennas great hdtv antenna

I have a Philips HDTV antenna that can cross me for terrestrial HDTV channels. However, there are in the large channels (Fox), but other terrible (CBS) can occur. What equipment do I need to buy me some of those channels better? Or is there any advice that I can not improve my current signal without buying a new item. Please let me know. I appreciate your help. - Thank you
