[TowerTalk] PEX tubing for antenna spacers?

[Larry Banks]

Thanks Don,

I guess I’ll go back to my first choice of PVC – it’s just three times heavier!

The milky white PEX tubing I have is very UV susceptible.  I used some short lengths to slip over RG 213 to protect it against chafing and it all cracked/split pretty quickly.

  Hi All,

  Has anyone used 1/2” PEX tubing (normally used for plumbing) as a spacer for open-wire line or fan-dipoles?  (PEX is cross-linked polyethylene.)

  It is cheap in 5’ lengths, easy to work, and passes the microwave oven test, so it isn’t conductive.  (The white stuff that I have microwave tested is not UV resistant, so there is a question about how long it will last outside.)

  As it is very light weight and seems to be fairly rigid, it looks like a good candidate for this purpose.  Any experience with this stuff out there?
