What's the design of your coat hanger antenna?
If it's working for everything else in the attic I'd first try moving it around a bit. Attics are not very antenna friendly. Sometimes even moving it a foot or up and down can make a tremendous difference. I'd also check connections and cable length.
If you're looking for a store bought antenna try the RCA-751 or Winegard Platinum 769 Series HD7694P pointed at about 325 degrees (measured with a compass).
