[TowerTalk] Split Loom as an anti-critter device?

[Mike & Becca Krzystyniak]

I have seen the copper shield of FSJ-4 separate at one or more of the rings,
making connections intermittent.
No evidence of physical damage, but there were a lot of thermal cycles.
The leading theory was metal fatigue. FYI, YMMV.

I concur that the Superflex PVC is thin and would not be the best choice for
long outdoor runs both on the tower or buried however I have been using FSJ4
for short outdoor jumpers for many years without issue. I assumed that
professionals like yourself also used this cable outdoors to connect 1 5/8+
Heliax to a device or antenna.

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.
