[TowerTalk] CNT400DB UV Resistance

I have a source of Andrew CNT400DB, which I was planning to use on the 
new tower. However, it's a "direct burial" cable, and I'm not sure the 
jacket is UV resistant. The specs say only that the jacket is "Black 
Polyethylene", while the non direct burial version is "Nonhalogenated 
Polyethylene", which I suspect has better UV resistance. I know from 
experience that the clear polyethylene used for coax center conductors 
has very low UV resistance. Does anyone have any information or 
experience with CNT400DB exposed to UV?
