My TVFool report is similar to the one shown here.  I went with the GE Attic Antenna  by Jasco - actually I ended up getting two of them.  Both are in the attic.  One is connected directly to my Tivo - no splitter, no amplifier - I wanted the Tivo to have the best possible signal.  The other one feeds into an amplified splitter that feeds out to 5 TVs in the house.  I tried several antennas before getting the GE/Jasco antenna and it has worked better than anything else I tried.  (My channels are a mix of UHF and High-VHF.)
