Just a note about something in this same vein that I ran into recently with leakage in cables with BNC connectors. I bought some 3 ft jumpers made up with BNC connectors and the connector has no tension when connecting to a BNC jack and once in a while I have to reseat the connector to try and get the connection back. How I noticed it was on a panadapter you could see images start to ingress Also on a antenna connection I was getting some hash from a switching supply in the receiver and reseating the BNC would clear thing up. Amphenol and good quality BNC's have some resistance when rotating the BNC ring and they are tight. The ones if have take very light torque at all to rotate and hence they are not always making a solid connection. They have no band marking so my guess is they are out of BY. There is one major manufacturer using these right now but are soon to replace them. 73 Mike K4PI
