If you can't put a yagi antenna up in your attic or crawl-space above the ceiling (like I do), a decent set of rabbit-ears is generally the next best thing. However, many folks report good results using the Magnum-D antenna, which is fairly expensive. Do not recommend an antenna amp. They amplify the noise in the incoming signal just as much as the music, so often a loosing proposition. Also, have you had the tuner section of your receiver aligned? If your Onkyo is 20 or more years old it will likely benefit from an alignment and recap. I'm 60 miles from the broadcast antennas listen to the most and have no problem picking them up with all my tuners (which are as much as 40+ years of age, but have all been recapped and aligned). 20-40 miles is not very far.
