1. A passive radio frequency (“RF”) subscriber drop unit, comprising:
a housing having a top wall and a plurality of sidewalls that define an open interior;
a female coaxial input port that extends from outside of the housing to the open interior of the housing;
a female coaxial output port that extends from outside of the housing to the open interior of the housing;
a printed circuit board mounted in the open interior of the housing; and
a ground wall that projects downwardly from an interior face of the top wall, the ground wall extending between the sidewalls, wherein the ground wall is electrically connected to a conductive ground plane of the printed circuit board.
