Claims14
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.
