a standard 31in antenna is 1/4 of a wavelength at 1 watt. since the frequency band is from 87.7 to 107.9 (in the U.S.) taking 3inches at a time helps keep the wavelength to height ratio intact to retain the best possible reception. that is until it is to low to have a proper ground plane at which point reception will be terrible.
