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.
No - never ever. Always LDF4 or similar.
Now if I had a bunch of FSJ4 and no LDF4, I would consider using it for
outdoor jumpers on a ham station because I would have the ends
weatherproofed well and would dress the jumpers in a way that ensured a
damage free lifetime.
But for a long buried run? No way.
