It's basic geometry.

But it's all related. A tall pole will let you get closer to the fence. A shorter pole will require you to be further back. Your location will determine the angle. The lower the angle the further back you need to be.

OTOH is the fence 6 feet high? That isn't very high.

metric distance calculator: fill in the parameters

height of dish
height of obstacle
distance from object

the graphic will show if you are to close to object with dish.
dish 1 meter up, fence 2 meter (1.8m) for 6 feet
distance would be 3 meter
so you could put up the disch 1 1/2 meter, easy when you want to adjust or exchange lnb's
and minimum 3 meters.
