the difference between the best and worst iindoor antenna is miniscule: more important is your location, the construction of your building, and the placement of the TV set in the apartment relative to the location of the transmitters.
FWIW I have had some success using a
Terk HDTVa, which is an amplified UHF-VHF undoor antenna, It uses a version of the famous SilverSensor UHF antenna for it's UHF reception. You will find that VHF digital reception with an indoor antenna is especially difficult, so you may have trouble with your local FOX affiliate.
