Most antennas that claim to be omni-directional actually are not, so don't expect any miracles. Besides, omin-antennas make for a lousy choice wherever multipath is a problem.
In any event, ALL of Boston's main stations have their transmitters located out near Newton, so, unless your viewing habits include any of the minor stations that transmit from elsewhere, a very DIRECTIONAL indoor antenna is actually what you need. Since you have signals very close by, you should NOT use anything with an amplifier. Terk HDTVi would probably be your best choice. From Cambridge, your aiming direction is southwest.
