Does anyone know how to cost effectively make a TV antenna that is capable of picking up local channels ranging from channel 2 to channel 36?

I am finishing off my basement and am looking to install ceiling speakers through out. (not surround sound, just music speakers) The speakers I am considering are stereo speakers (each speaker plays both the left and right channel). Since each speaker plays both channels I believe that I need to run 2 pairs of wires to each speaker, one pair for the left channel and one pair for the right channel. My goal is to install 4 of these speakers, which means that I need to run a total of 8 pairs of wires and this equates to 4 sets of speakers. [B]My question is how do I run 4 sets of speakers off of one receiver? [/B] The receivers that I have been looking at are usually set up to run 2 sets of speakers A and B? Thanks for any and all help! Darryl :-)
