Abstract
A carrier for installing an RFID tag in a utility marker tube provides a centering plate fitting against an upper edge of the tube and oriented and positioned either by inner tube walls and/or the outer tube wall periphery to locate a downwardly extending transducer support tab holding the transducer within the tube. The centering plate may be held in place by a separate or integrated cap retaining the centering plate while sealing the tube against environmental contamination.
