Re: how would you set up?
First, if you don't have the wind in your favor, don't even bother...(but that should be a given)
2nd, coyotes would prefer to not travel up a hill to inspect a noise, so you're going to get a lot of coyotes stopping out there between 100-500 and just looking. They have cover, plenty of cover, and they will circle that hill side to the downwind area before they will just head up the hill.
That type of set up is better for an e-caller where you can put it 50-100 yds down that first road, and hope to coax a predator into circling where you can still see it.
Not saying it won't work, but you're not going to have very good luck unless the conditions are prefect...especially when they have the element of cover working in their favor...despite your elevation advantage.
