Current Philly products are now somewhat different than the older
product that was supplied with KLM antennas--mostly having to
do with the jacket thickness.   So OD of the jacket is not a
good correlation with strength--depending on vintage of the
cable.  The strength comes from the diameter of the Kevlar core.

You can contact Ken Knight for Phillystran info and his
address is on their web site.     http://www.phillystran.com
Not a very good web site--not much in the way of technical "meat"
there.
