Looks very much like a Loran-C receive antenna.
Loran-C worked down in the long wave band, around 100KHz. The circuitry in the base was often an amplifier/tuned filter to help pull the signal out of the noise.
Loran C is mostly shut down. The antenna might be useful for parts or to build something else. The circuit at the base would need to go since it'll limit operation to the long wave band.
For a $1, you might be able to find some use for it. Removing the circuit at the base might make it into a decent low band (30-50MHz) antenna.
