The nickel-plated brass body and solder shield termination give a clean ground reference; the PTFE dielectric maintains consistent dielectric constant across the frequency band. For a BNC, 4 GHz is the practical ceiling — above that the interface geometry starts to support higher-order modes, so stay under that ceiling for a clean VSWR.
The 1274727-1 is rated to 4 GHz maximum frequency. The BNC interface geometry limits clean signal transmission above that ceiling.
