Abstract: Various embodiments include an apparatus for mounting a water-meter antenna in a boundary box lid, including an inverted vessel adapted to both receive said antenna and orient said antenna such that in use the electro-magnetic radiation substantially propagates out of a boundary box covered by the boundary box lid, wherein either: i) the inverted vessel further comprises resilient mounting means adapted to secure the antenna in said vessel; or ii) a carrier is provided that is adapted to receive the vessel, the carrier preferably comprising resilient mounting means adapted to secure the inverted vessel in said carrier.
