There is a long, thin, rubber-y line wrapped around/connected to the water line pictured below.
Other angle:
The piece in question is loosely hanging via a zip tie on my main water line about shoulder height and can be moved up/down easily.

Allow me to nudge you. How long is that pipe? Where is the ground? Why would a water company use ham radio frequencies to transmit data? How is the contraption feeding signal into the pipe with plastic and no matching network? Plumbing is grounded so it's conceivable the pipe is being used as a ground, but then it wouldn't matter if you moved it up or down a little. This is NOT and antenna.
