Re: [TowerTalk] PEX tubing for antenna spacers?

[Patrick Greenlee <patrick_g@windstream.net>]

Don, Garden variety PEX (Cross-linked polyethylene) is not UV stable and 
should never be purchased from a supplier who stores his stock outside.  
There are however available sources of UV stabilized PEX. Not being the 
most trusting ("Trust but verify," Ronald Reagan) person I'd paint 
anything I was not sure of with UV stable paint.
