Default Grounding A BNC Coax Cable End ?

I have a bnc coax cable from a receiving (only) antenna that ends up at
a plastic cased switch box. The box has no convenient grounding point.

I would like to ground the bnc of the coax end.


Bob-

The BNC crimp connector I'm familiar with has a cylindrical ferrule that
first slips over the Co-Ax. The connector body is then pushed onto the
cable with a smaller cylinder sliding under the Co-Ax shield. Then the
Ferrule is slid back over the shield end and inner cylinder, and finally
crimped.

I don't think it would be practical to insert a wire to be captured in
the crimping process. Although it might be possible to solder a wire to
the ferrule after it had been crimped, the Co-Ax dielectric would
probably be deformed by the heat.

Does the BNC connector have a mate in the box? If so, the mate might be
a better place to attach a ground wire, especially if you want to
disconnect the BNC at some point. If not, you could install a female
connector on a grounding plate, that has no connection to the Co-Ax
center conductor.

Ground wire with large alligator clip gripping BNC connector?
