I need to conect to the braid of RG-59B/U with some kind of clamp over the cable's braid. The interface is to a circuit board. Soldering the braid is not viable because the inner dielectric could melt and this cable is supporting 3 kV. Can anyone offer a suggested clamp, manufacturer and/or part number?
It's too bad the OP didn't post a picture of the interface connection in question. It's kind of like a shot in the dark as to guessing at what may or may not work for him. At 3kV though, it almost sounds like he needs some type of modified spark plug connector.
