Without knowing exactly how far you are away from your transmitters it's hard to recommend something. I suggest asking the folks over at avsforums

That thread under "HDTV-HDTV Technical- EV's Best Top Rated HDTV Indoor Antenna Review Test Round-Up Guide" is FULL of very smart people who can help you if you give them a full profile. There are also sections of AVSforums that are specific to different marketplaces and the reception challenges that each location has.
That being said, nothing worked for me until I got my DB2. I tried around 10 of the top-of-the-line models until I installed that (indoors). Everything now comes in crystal clear.
If imprinted foil seal under cap is broken or missing when purchased, do not use.
