1. A coaxial cable connector comprising:
- an outer connector body;
a female end of the connector is for engaging a male coaxial cable connector;
the connector female end having a waveguide with an aperture for receiving a center conductor of a coaxial cable;
the waveguide made from a non-metallic base bearing an RF shielding material;
wherein a diameter of the aperture is in a range 1.5 mm to 3.0 mm; and
,wherein the waveguide is configured to shield connector body internals from ingress of radio frequency signals in a range of 1 to 1000 megahertz.
