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.

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.
