LMR-400-UF uses a rubberized thermoplastic elastomer jacket for flexibility.
Unfortunately it has been reported on towertalk to have poorer UV resistance
than other coax jackets such as (LMR-400) PE or (RG-213) PVC.
RG-213 melts? Please explain. I have been using Belden 8267 RG-213 both on
the tower (in hot climates) and in the shack for decades and I have not seen
anything even resembling melting.

it's the LMRx00UF (ultraflex) you want, not plain LMRx00.
I use LMR600UF as a jumper for my 6m antenna, at the top of the tower, and
it's been doing quite well. It's made of a stranded copper core and copper
outer conductor. No aluminum.
It's the non-UF ones that use aluminum, and also their core is made of
copper platted aluminum rod.
p.s. RG213 has been known to melt...
