Bigger antenna helps the most on improving the signal, where larger signal to noise ratio (snr) is the goal. The only real question for your antenna is in choosing which fraction of a wave (1/4, 18, etc) you can live with for antenna length to get the best performance without vehicle operation problems.

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.

Fwiw On boats it’s about how high it is, so it can get past the horizon
