It gives a map that should give you direction, you can decide which stations matter most if they are in multiple directions. Mostly, cities tend to group transmitters together so you can use antennas effectively. You may have some channels listed from other nearby cities.
The Leaf should be enough for yellow range. But not if it is buried in the basement or there is a large brick building right next to you, in the way. Basically, you want it to be line-of-sight as much as possible.
