Abstract: An elongated stabilizer is coupled to a generally vertical pole or stake, and disposed transverse to the pole or stake, extending in opposite directions therefrom, for engagement with the ground surface. The stabilizer may tilt relative to the post to accommodate inclined terrain. The stabilizer is provided with means defining four guide paths for four separate anchor rods, the rods being elongated linear members with heads at one end. All of the guide paths are disposed in planes generally perpendicular to the longitudinal axis of the stabilizer with two such guide paths being provided at each end of the stabilizer on opposite sides of the post. The two guide paths at each end of the stabilizer are provided to guide the rods at angles relative to a plane common to the pole or stake and the stabilizer, with the paths being inclined at opposite angles relative to that plane so that the anchor rods are driven into the ground at opposite angles relative to that plane.
