Here' a chart that lists lengths of dipole rods for a given VHF channel.

I agree with elmo, any antenna with a single dipole for VHF reception can be expected to perform about the same, regardless of cost, advertising clams, amplification, etc.
Antennas that are designed to support UHF only (example, CS1) will offer little if any VHF reception.
After following elmo's advise, to patiently try adjusting and searching for a 'sweet' spot, you may be forced to consider using a small 'outdoor' type antenna in your apartment. The RCA ANT-751 and Antennacraft HBU-11 come to mind.
