Have you tried plain old rabbit ears? Our signals are very good since the majority of the stations are now located on the super antennas on Lookout Mt. At our house I'm getting -20dBm to -30dBm signal strength with just rabbit ears.
I will be putting an antenna on the roof, though, to get it out of sight. But I've found I will only need a dipole (I'm doing a folded dipole to make it even smaller) and not a yagi. MUCH easier to get out of sight.
With the stations collected pretty closely you could point a yagi at Lookout inside your attic or garage and still get good strength.

"Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty. Nobody is able to achieve this completely, but the striving for such achievement is in itself a part of the liberation and a foundation for inner security. " --Albert Einstein
