Abstract

The present technology discloses a utility meter with an externally-mounted antenna that is electrically insulated to prevent conduction outside of the meter. The antenna is coupled to a communication device that is positioned adjacent to an inside surface of a meter cover and that is configured to connect to a metrology board. The utility meter also comprises an antenna, having one or more leads for coupling with the communication device, the leads extending through openings in the meter cover. The communication device is advantageously positioned to minimize or eliminate radio frequency interference with the metrology board.

Claims

1. A utility meter, comprising:

a cover comprising an end wall and an open end, wherein the end wall is opposite the open end and the end wall is vertical;

a communication device positioned adjacent to an inside surface of the end wall of the cover;

an antenna housing fixedly attached to an outside surface of the end wall of the cover, wherein the antenna housing extends horizontally across a lower half of the end wall of the cover and projects outwardly from an outer surface of the end wall of the cover; and

an antenna received under the antenna housing such that the antenna housing covers an upper surface of the antenna, wherein the antenna is mounted externally with respect to the cover by the antenna housing, and wherein the antenna is coupled to the communication device through the end wall of the cover.

2. The utility meter of claim 1, wherein the antenna further comprises a hook configured to engage the antenna housing.

3. The utility meter of claim 2, wherein the hook is configured to engage the antenna housing to position the antenna in the antenna housing.

4. The utility meter of claim 2, wherein the hook and the antenna housing respectively include one of a protrusion and a notch, wherein the protrusion is configured to be received in the notch to facilitate the hook engaging the antenna housing.

5. The utility meter of claim 2, wherein the antenna is enclosed in a molding and the hook is attached to the molding.

6. The utility meter of claim 1, further comprising a grommet configured to receive an antenna lead and to seal a point of passage of the antenna lead through the cover for connection to the communication device.

7. The utility meter of claim 6, wherein the grommet is configured to allow for insertion of the antenna lead at one or more angles.

8. The utility meter of claim 6, wherein the antenna is configured to couple to the communication device by attaching the antenna lead to a surface on the communication device.

9. The utility meter of claim 1, wherein the antenna housing is electrically non-conductive.

10. The utility meter of claim 1, wherein a lead extends from the antenna through the cover and into an interior volume of the cover.

11. The utility meter of claim 1, wherein the antenna is perpendicular to the end wall.

12. The utility meter of claim 1, wherein the antenna housing includes a first eave covering the upper surface of the antenna.

13. The utility meter of claim 12, wherein the antenna is enclosed in a molding and the molding includes a second eave that is configured to at least partially close an opening in a bottom of the antenna housing.

14. The utility meter of claim 1, wherein the antenna is enclosed in a molding and the molding is configured to attach to the antenna housing.

15. The utility meter of claim 14, wherein the molding is configured to at least partially close an opening in the antenna housing.

16. The utility meter of claim 14, wherein the molding is configured to position the antenna in the antenna housing.

17. A utility meter cover, comprising:

an end wall and an open end, wherein the end wall is opposite the open end and the end wall is configured to be vertical when the utility meter cover is attached to a utility meter;

an antenna housing fixedly attached to an outside surface of the end wall, wherein the antenna housing extends horizontally across a lower half of the end wall and projects outwardly from an outer surface of the end wall; and

wherein the antenna housing is configured to;

receive an antenna under the antenna housing such that the antenna housing covers an upper surface of the antenna; and

mount the antenna externally with respect to the utility meter cover;

wherein the utility meter cover is configured to allow the antenna to be coupled to a communication device of a utility meter through the end wall; and

wherein the utility meter cover is configured to cover the communication device such that the communication device is positioned adjacent to an inside surface of the end wall.

18. The utility meter cover of claim 17, further comprising a grommet configured to receive an antenna lead and to seal a point of passage of the antenna lead through the utility meter cover for connection to the communication device.

19. The utility meter cover of claim 18, wherein the grommet is configured to allow for insertion of the antenna lead at one or more angles.

20. The utility meter cover of claim 17, wherein the antenna housing is electrically non-conductive.

21. The utility meter cover of claim 17, wherein the antenna housing includes a first eave configured to cover the upper surface of the antenna.
