RJ45 is a loose fit connector and is a standard failure point during shock and vibe testing (bounce causes the contacts to come apart). I don't really like it for the radio connection, but we have little choice here.

I'd prefer a connector like the Cannon / Amphenol MS3112E12-10P connector.

Standard barrel connectors have 360 degree connection so vibe failures are minimized and the only common failure point is if the connector totally pulls out of the socket.
