Claim 0:
1. An RFID marker system comprising:
a tubular post of a radio-transparent polymer material adapted for partial insertion in the ground to extend upward therefrom, the tubular post providing outer walls defining an internal volume;
a centering plate receivable at an upper end of the tubular post to be supported by the upper end of the tubular post;
a transponder support tab attached to and extending downwardly from the centering plate when the centering plate is received at an upper end of the tubular post, the transponder support tab extending within the internal volume to present a vertically extending surface sized to receive an RFID tag thereupon; and
an RFID tag attached to the vertically extending surface; and
further including a cap having an upper wall and having at its perimeter downwardly extending walls adapted to slide over the outer walls of the tubular post of the upper end of the tubular post therein to capture the centering plate between a lower surface of the upper wall of the cap and an upper surface of the upper end of the tubular post.
