VSWR effect on transmitted power
Cable Fixing
Cable fixing onto LEMO connectors is determined by the connector model. This is achieved either with a cable collet
system or with hexagonal crimping (MIL-C-22520F, type 2).
The collet system cable fixing is made without any special tooling. The crimping method guarantees a good electrical
continuity of the shield which improves greatly the shielding efficiency of the cable/connector link.
