A telemetry antenna system for transmitting data from underground utility meters includes a telemetry board, a radiator assembly connected to the telemetry board and a housing assembly for housing both the telemetry board and the radiator assembly. The radiator assembly preferably includes two metallic plates separated by an air gap dielectric and connected by a plurality of inductive shunts. Capacitive tuning pads are also included on the plates and are connected by shunts. The housing assembly preferably includes a cylindrical base having an integral annular ring. The base houses the telemetry board. The radiator assembly is operably connected to the telemetry board and is housed and located within a radome which sealingly engages the annular ring. The radome is sealingly secured to the annular ring of the base by a retaining ring which is tightly, releasably fastened to the annular ring of the base. The housing assembly may include additional elements such as an end cap, base lock, spine and/or bulkhead. |
