Had to look it up, but realize that a "leaf" antenna is another name for the TV "blade" antenna I suggested. Glad you had a (brief) initial success! Please report more details here when you get back, such as which band(s) it's working best on, where how you mounted it (window, attic, wall), etc.
It's interesting to me that many people don't realize that you can use TV antennas for scanners and save a lot of money and time. Probably not so interesting to the folks who make the $150-300 special-purpose scanner/commercial antennas.
