The dimmer may be configured to contain a variable number of controllably conductive devices. The dimmer may include a yoke that defines a first plane and an antenna that defines a second plane that is substantially parallel to and spaced apart from the first plane. The yoke may have a flange that is oriented angularly offset relative to the first plane and provides a plurality of mounting locations for controllably conductive devices. The antenna may provide the dimmer with a first wireless transmission range. The dimmer may include a faceplate that cooperates with the antenna to provide the dimmer with a second wireless transmission range that is broader than the first wireless transmission range. The dimmer may include a button assembly that is supported independently of the yoke. ## Claims ### Claim 1 A wallbox-mountable electric load control apparatus comprising: a faceplate member having a front surface and a rear surface, the faceplate member couplable to an electrical wallbox; radio frequency transmitter circuitry disposable within the electrical wallbox; an antenna structure coupled to the RF transmitter circuitry, the first antenna structure having a transmission range, the first antenna structure disposed within the area of the faceplate; and an electrically conductive element isolated from the RF transmitter circuitry, the electrically conductive element to cooperate with the antenna structure to provide a transmission range greater than the antenna structure transmission range, the electrically conductive element disposed within the area of the faceplate. ### Claim 2 (depends on 1) The wallbox-mountable electric load control apparatus of claim 1, further comprising: a yoke structure couplable to the electrical wallbox. ### Claim 3 (depends on 2) The wallbox-mountable electric load control apparatus of claim 2 wherein the yoke structure further comprises: a “C-shaped” yoke structure couplable to the electrical wallbox. ### Claim 4 (depends on 2) The wallbox-mountable electric load control apparatus of claim 2 wherein the “C-shaped” yoke structure further comprises: an electrically conductive shorting member disposed across the open portion of the “C-shaped” yoke structure to form an electrically conductive loop structure. ### Claim 5 (depends on 2) The wallbox-mountable electric load control apparatus of claim 2, further comprising: an electrically conductive member conductively coupling the electrically conductive element to the yoke structure. ### Claim 6 (depends on 1) The wallbox-mountable electric load control apparatus of claim 1 wherein the electrically conductive element is positionable proximate at least a portion of the rear surface of the faceplate member. ### Claim 7 (depends on 1) The wallbox-mountable electric load control apparatus of claim 1 wherein the antenna structure comprises a monopole antenna structure. ### Claim 8 (depends on 7) The wallbox mountable electric load control apparatus of claim 7 wherein the monopole antenna structure comprises an open outer loop that having a first end and an open inner loop that includes a second end, the open outer loop coplanar with and at least partially surrounding an open inner loop. ### Claim 9 (depends on 1) The wallbox-mountable electric load control apparatus of claim 1, further comprising: a controllably conductive device disposable in the electrical wallbox; and control circuitry disposable in the electrical wallbox, the control circuitry to reversibly transition the controllably conductive device between a CONDUCTIVE state and a NON-CONDUCTIVE state to adjust power delivered to an operatively coupled electric load device. ### Claim 10 (depends on 1) The wallbox-mountable electric load control apparatus of claim 1: wherein the faceplate member comprises a planar faceplate member; and wherein the electrically conductive element comprises a planar electrically conductive element. ### Claim 11 (depends on 10) The wallbox-mountable electric load control apparatus of claim 10 wherein the planar electrically conductive element includes at least one aperture. ### Claim 12 (depends on 11) The wallbox-mountable electric load control apparatus of claim 11: wherein the antenna structure comprises a planar structure defining a first plane; wherein the faceplate member comprises a planar member defining a second plane, the second plane parallel to the first plane; and wherein the electrically conductive element comprises a planar member defining a third plane, the third plane between the first plane and the second plane, the third plane parallel to the first plane and the second plane. ### Claim 13 (depends on 2) The wallbox-mountable electric load control apparatus of claim 2, further comprising an adapter member; wherein the adapter member comprises a non-electrically conductive member physically couplable to the yoke member; wherein the faceplate member comprises a faceplate member physically couplable to the adapter member; wherein the rear surface of the faceplate member comprises a non-electrically conductive material; and wherein the electrically conductive element is disposed between the adapter member and the rear surface of the faceplate member.
