I'm using an AudioPrism 8500. It's an indoor antenna that is a large black column with multiple elements inside. An offboard switch determines element sensitivity combinations that make the antenna directional without having to physically rotate the unit. The 8500 may be out of production, but perhaps a used one might be available.
I live between two large but relatively distant cities. There is also a noisy local station close to my home. The antenna helps be pull in city broadcasts while rejecting the local signal. I also have a Magnum Dynalab MD 205 Signal Sleuth, a tunable booster that helps me further deemphasize the local broadcast.
I have found that antenna location choices can often be more important than antenna hardware. For example, even the simplest antenna mounted outside can often do better than a fancy indoor antenna. Where an antenna is located within a room is also key, as well as its orientation. Also, city users have different requirements, such as multipath/reflection rejection, versus suburban users who may be more interested in weak signal reception. This would generally imply different antenna solutions. Good luck.
