 This higher power also translates into smaller receiving dishes and points out a generalization between a satellite's transmission and a dish's size.As the power increases, the size of an antenna's dish will decrease.This is because the purpose of the dish element of the antenna is to collect the incident waves over an area and focus them all onto the antenna's actual receiving element, mounted in front of the dish (and pointed back towards its face); if the waves are more intense, fewer of them need to be collected to achieve the same intensity at the receiving element.
