91 Accord: Poor Radio Reception

The subject says it all, but my first specific question is: is there a
factory antenna booster? I am putting in a new radio and I didn't hook
any of the power antenna connections up (I have a non-power antenna,
although when I opened up the back to take a look there was a power
unit laying in there with installation instructions!). If there is no
factory antenna booster, than I should get at least reasonable
reception the way it is hooked up.

BTW, the radio that was in it (also not factory) also had poor
reception, although it seemed to happen all of a sudden one day.
