Agree with the others, just straighten it as best you can, except: look carefully at the parallel plate capacitor where the coax attaches. There, you should see a sandwich of aluminum-bakelite-aluminum. If there are bends or damage in that area, send it back.
Make sure the ground arm is under the screws that attach the tip to the wing.
As others have said, this is a fine antenna for ILS work, and pretty good for VORs.
