A pit mount interface device includes a body having a head and an elongate stem extending from a bottom surface of the head. The elongate stem is sized and configured to be received in and extend through a hole formed in a cover of a pit. A nut defines a central aperture that is sized and configured to receive the elongate stem of the body. A passive radiator is disposed within the body and configured receive a radio frequency (RF) signal transmitted by an automatic meter reading (AMR) device located below the cover through inductive coupling and to radiate the RF signal from a position located above the cover of the pit.
