Let the vertex of the parabola be at the origin and its axis along the x axis.
An equation would be y%5E2=4px
Where p is the distance from the center of the dish to the focus.
Since the point (38,150) lies on the parabola, we have
150%5E2=4p%2A38
p=5625%2F38=148.03
Equation can be represented by y%5E2=11250x%2F19
