The connector of claim 1, wherein the connector includes a cable fastener member movably coupled to the connector body. 3. The connector of claim 1, wherein the coupler contacts the body. 4. The connector of claim 1, further including a sealing member, positioned between the coupler and the connector body, the sealing member providing a physical seal and barrier to ingress of environmental contaminants into the connector. 5. The connector of claim 1, wherein the continuity member helps ensure a continuous electromagnetic shield from the coaxial cable to the interface port, even when the coupler is coupled to the interface port by only a few threads. 6. The connector of claim 1, wherein at least a portion of the continuity member is configured to flex and retain consistent physical and electrical contact with a conductive surface of the rotatable coupler, to help ensure continuity of an electrical path between the interface port and the coaxial cable, even when the coupler moves. 7. The connector of claim 1, wherein at least a portion of a component of the connector is formed having a conductive coating. 8. The connector of claim 1, wherein the continuity member includes a disc-like portion and a resilient flexible portion connected to the disc-like portion and configured to arch away from a plane of the disc-like portion of the continuity member. 9. The connector of claim 8, wherein the continuity member includes a plurality of flexible portions, the plurality of flexible portions forming symmetrical portions each arched above the general plane of the disc. 10. A coaxial cable connector for coupling an end of a coaxial cable, the coaxial cable having a center conductor surrounded by a dielectric, the dielectric being surrounded by a conductive grounding shield, the conductive grounding shield being surrounded by a protective outer jacket, the connector comprising: a connector body, having a forward end and an opposing rearward end, the rearward end configured to receive a portion of the coaxial cable;a post, configured to engage the connector body, the post having a forward end including an external annular protrusion and a rearward end, the rearward end configured to be inserted into an end of the coaxial cable around the dielectric and under at least a portion of the conductive grounding shield thereof to make electrical contact with the conductive grounding shield of the coaxial cable;a nut, rotatable relative to the post and the connector body, the nut including a forward nut end portion configured for coupling to an interface port, a rearward nut end portion, and an internal lip, the internal lip having a forward lip surface facing the forward end portion of the nut and a rearward lip surface facing the rearward end portion of the nut; anda continuity member having a nut contact portion positioned to electrically contact the nut and positioned to reside around an external portion of the connector body when the connector is assembled, wherein the continuity member helps facilitate electrical grounding continuity through the body and the nut and helps extend electromagnetic shielding from the coaxial cable through the connector to help prevent RF ingress into the connector. 11.
