In my experience, both crimp/crimp and clamp/solder connectors will fail if subjected to repeated flexing if it exceeds the cable manufacturers' recommended bend radius of the cable. Even if the shield is truly immobilized by the crimp or clamp like it's supposed to be, during a bend the outside of the bend radius will be subjected to stretch load and the inside will be subjected to compression load. If the bend radius limit of the cable is exceeded, individual strands of the braid on the outside of the radius can fail, and over time will fail to mechanically support the cable and the connection.
If you have a cable that will be subjected to use that could cause the shield to fail from the above cause, it is recommended that you use an appropriate radius control boot. Most professional test cables will have this. Take a hint. If you want a cable to survive constant bending, boot it with several layers of heat shrink to help with the above problem. Also, be sure to follow the manufacturers' recommendation for strip length for the center conductor and shields. I've seen some pretty poor installations caused by not properly capturing the shield in the crimp and not having the proper pin placement for the center. The company I work for uses hundreds of thousands of crimp BNC connectors for signals from DC to 1.5 GHz. They are EXTREMELY reliable and consistent. 73 de N1FNE -----Original Message----- From: john_k2gvp [mailto:[EMAIL PROTECTED] Sent: Tuesday, December 02, 2003 4:53 PM To: [email protected] Subject: [Repeater-Builder] Re: crimp/crimp or clamp/solder? Sean: My experience in 30+ years in electronics has been the crimp connectors will not take as much use as the clamp because the shields will eventually break at the crimp. The clamp/soldier connectors are a more mechanically stronger cable to connector attachment. I have made and purchased cables and have found the above to be true in both cases. Another feature of the clamp connector on a cable is can be repaired. Hope this helps. 73, John K2GVP I am interested in getting opinions on which type of coaxial connectors > are prefered and why. > Thanks, > Sean Your use of Yahoo!
