The Zenith Silver Sensor, available in some stores, performs quite well for an indoor UHF antenna, IMHO. With indoor antennas, placement is *everything*. If the antenna can be placed near a window that is facing the antenna towers, that would be excellent.
I agree on the Terk statements. They are packaged well, look nice, and seem to have convinced most retailers to carry them, but all that has nothing to do with quality of reception, which through a Terk -- is poor to fair (at best). There are *much* better and less expensive antenna options.
