Go for it. Right now I'm receiving a ship on the river 12.5 miles upstream from my house, through trees and buildings, and my antenna isn't even mounted properly. I'll probably receive from much farther out if I mount it on the roof like I've been meaning to. If you can see the ships, you'll definitely receive them. 3-4 miles is nothing.
