While you would catch a "larger amount" of signal with a bigger antenna, you would also catch an equally larger amount of noise unless the antenna is focused more on the source of the signal. The task of the dish antenna is to provide stronger usable signal not in absolute terms, but in relation to the background noise. The gain of the parabolic antenna is proportional to the diameter of of the dish and inversly proportional to the beam width. Therefore a bigger dish means a more focused (narrow) signal.
