Abstract
A device for electronically marking a buried object, such as a service drop cable, comprising a reel for retaining the cable in a known position and orientation, and a transponder positioned at a predetermined location and orientation with respect to the cable wound on the reel. A foam shield may be used to provide a visual indication of the presence of the device, and an anchor may be affixed to the reel to secure it more firmly in the ground. The transponder can be located within the hub of the reel. The transponder can be active or passive.

13. A system for detecting and locating an underground service drop cable, comprising:
-
a transponder reel housing having a generally cylindrical, hollow hub with a passive transponder located therein, and having two generally circular, parallel plates attached to said hub to define a reel for the cable, wherein said transponder is positioned at a predetermined location and orientation with respect to said hub to reduce electromagnetic influence of said transponder by the cable; and a transceiver for energizing said transponder and sensing a return signal therefrom.
