I bought these BNC cables to replace some self-made cables that I used some cheap BNC connectors from China to try to keep cost down. The result was a very poor connection on the connector that allowed signal to drop. I decided to replace my cable sections by splicing in with these pre-built 4-BNC cables from Monoprice and they worked perfectly. These have a outer stranded shield, a foil shield, 3 strands of teflon, individually jacketed signal cables all within the main jacket. This helped preserve a good quality signal, and the BNC connector itself was well built, and tight to fit. I like how the jacket to connector is totally sealed. All of this, and they were probably more cost effective in the long run, I wish I found these first.
