You mention 600 UF.  I've used a fair amount of it and found very poor 
life with the stuff.  Poor resistance to UV and easily abraded if it 
rubs against something like the tower top in a rotator loop.

I had 5 runs through a rotator loop that laid on top of a 45G top 
plate.  After 6 years (give or take a tad) the shield was showing 
through several of the runs.

I figured I'd make jumpers for the station with the one piece that 
looked good.

I'd made several jumpers when I cut a third to length,  It looked like a 
gray powder around the cut, so I stripped the jacket back a ways.  The 
foil was almost completely gone, but I could find no holes in the 
jacket.  It had to have worn down to the point of being porous because 
this was a piece from the middle of a run and the ends were good so the 
water didn't come in from the connectors.

73 and good luck,
