A ground anchor system for anchoring a post comprises a base plate, a housing extending above the base plate, an anchor extending below the base plate, the anchor comprising a tapered helix having a thread encircling a tube which tapers inwardly towards the lower end of the anchor, and a boring tip at the lower end of the anchor. The tapered helical thread of the anchor firmly engages with the ground into which it is threaded to provide a solid support to a post inserted in the housing. Helix taper and length, and thread taper and pitch may be selected to optimize retention and lateral support of a post in a particular ground type.
