Marty,
I believe this is the Super Flex variety. It is UV rated, but the jacket
is very thin compared to regular Heliax. I use this for internal jumpers
because it is really 100% shielded.
I do not use this outside, nor the 1/2" variety, because the jacket will not
take much abuse. This is speaking commercially and for ham radio use.
