OK, it's a terminology issue.
There is:
1) Smoothwall hardline.
2) Spiral corrugated hardline (like FSJ4).
3) *ringed* (my term) corrugated hardline (like LDF4).
FSJ4 is #2, and water will travel under the jacket the full length of
the cable. #3 will not allow that.

According to the following Commscope document, SuperFlex is corrugated. I have
a bunch outdoors. Like all other hardline at my station, the connectors are
sealed with at least 4 layers of silicone and vinyl tape, over connectors with
silicon O rings preventing water intrusion down the shield.

New to the Northeast, and all the critters that eat...well, everything
when it gets cold enough.
I am planning on running a length of FSJ-4 (1/2" Andrews superflex)
from the house to the end of the back yard. In the spring I will bury
it, but until then it needs to sit on top of the lawn. I worry about
something eating through it--although it's pretty hefty for something
to chew on, it wouldn't surprise me.
I was thinking I'd put the cable in say a 1" or 1-1/2" split cable
loom, just as an extra cover to fend off teeth. Dumb? Unnecessary?
What does the Collective Wisdom say?
Superflex style cables, where the shield is a spiral configuration rather than
corrugated, is not a good choice for outdoor use. If water gets under the
jacket either from the ends or thru a jacket penetration, it will run end to
end, get into the connectors, and ruin the cable.
The jacket is thin to help with the flexibility, but is easily damaged.
Great for indoor jumpers - not much else.
Use LDF4 if you can.
