I use square grey PVC rod from McMaster, UV proof, easy to drill, your
choice 3/8, 1/2" or larger. My fan dipole has 30" separation at the
ends so I used 3/8".

another choice is sch80 pvc pipe in 1/4 or 3/8" ips sizes. McMaster
again, probably cheaper locally.
Common PEX, I think regardless of color, is not UV proof as others have
mentioned.

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?
