It can mean that, but not in this case. For one thing, wire used as a counterpoise for antennas must not be more than a couple inches below the surface or they won't work. They work the best above the ground. And, despite what Wiki says, antenna counterpoises do not have to be isolated from the ground to work. Most, in fact, are electrically bonded to the ground or a substitute for the ground (vehicle body).
