It is not exactly flexible and more suited for permanent instalations. If you do not have to go to 25GHz then you can use their 3/8" or 1/2" for even lower loss (and less flexibility) but the high frequency performance begins to deteriorate.
That particular type of coax is corugated and uses closed cell dielectric material to minimize hygroscopic affinity. Another vendor of low loss coax cables is a German manufacturer "Rosenberger" ===== Best Regards Hans Mellberg EMC Consultant __________________________________________________ Do You Yahoo!?
