For AM radio, the longer the antenna, the better the reception (assuming the trimmer has been adjusted per the instructions in the owner's manual). Some of my older cars (unmentionable on this list) have extremely long antennae, and astonishing sensitivity to far away stations, so long as I'm driving away from any noise pollution (cities etc.). For FM antenna length, there is a critical dimension, and that is 31 inches, as is also stated in your owner's manual. These lengths are determined by the wavelength of the transmitted signal. Every electric power antenna of which I am aware will retract fully into the fender when it is in good condition. Vacuum operated power antennae leave about 4 inches sticking out of the fender when fully retracted, but I don't think these are used on Chrysler products, at least not after 1952 or so.

I'm 6'1" tall and when that '62 Imperial AM antenna is fully extended, I can barely reach the tip of the antenna with my index finger, and only when I stand on tip-toed.
