As I understand it:

Short antenna is shorter range but works best in hilly terrain (signal is 'rounder ')

Long antenna is long range but works better over flat terrain (signal is horizontally 'oblong').

I realise this is actually a function of the dbi but I believe length is inversely related to dbi.
