That style of mount is meant to fit between the hood and fender. So you'd pop the hood, screw the mount down to the fender so it sticks up through the gap when the hood is closed. It involves drilling but they are effective mounts, probably the most common style in my area.
*edit- Also the adjustable part is facing the wrong way, it would prevent the hood from opening or closing. Your 2nd picture illustrates it best. Just unscrew the bolts, flip the top adjustable part around so the top flat area the antenna will bolt into is facing outboard, away from the hood, and bolt it back down.
