Is there a way to increase the radio signal range on the toyota corolla 2004 by any chance? have noticing a few issues with getting signal in and around exeter when i go to the toyota dealership.

Check the aerial mast, the plastic tends to crack over time

As Bob mentioned, the aerials have a tendency to disintegrate, but you can also find that the screw-in fitting has corroded and thus reducing the strength of the signal. So, it's worth unscrewing the aerial and clean up the threads. If the old one looks past its prime, the 2004 Corolla takes a normal threaded aerial so you can buy and fit pretty much any aftermarket model.

Does the length matter?

No, not really. The original is about 30 cm long, which I think is a good compromise between good reception while not looking silly or being in the way. There are shorter stub aerials that look a bit more modern and won't be in the way.
