[TowerTalk] 9913F Coax Specs

[LEEWICAL@aol.com]

      I am sorry I cannot remember which reflector where I first read about
the newest flexible  BELDEN coax. So I had more questions so I contacted
their marketing engineers and obtained more specs which, if I may, share with
you. BTW I don't have shares of stock in BELDEN!
