[BC] Air-Dielectric Sections

[Rob Atkinson]

Phil,

just trying to learn something--how is rigid line normally run below grade?  
That is, what is it usually placed inside of?

thanks,

Mike,

Maybe I'm dense, but I thought he meant air dielectric Heliax.

Who would consider running 3-1/8" rigid in u/g conduit? It
makes no sense and would cost a fortune, even if the line
was free. (i.e., surplus in the company)

IMHO bare, unprotected PVC is always unwise. Some rodents
seem to like it, and in areas of spring thaw, rocks can
abrade it to destruction. Fiber duct would be less expensive
than laying properly protected PVC. This is a case of the
low cost solution being the most expensive solution.
