Hello,

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.

I can rig "something" up of course, but was wondering if anyone might
know of a bnc connector which perhaps has a wire lead coming out of it
for this kind of purpose, or a screw terminal, or something for
grounding the bnc shell (and hence the coax shield) ?

Looked, but couldn't find anything appropriate.

Thanks,
Bob

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.

Hi Bob,

The female BNC bulkhead connector often comes with a star/flat washer
style of solder tab.

There's also this style which is overkill for you application.
As Richard said the star/solder tab will work

Not the best picture but, on the expanded view you can see
a ground tab with hole and the center pin.

Ground wire with large alligator clip gripping BNC connector?
