[BC] Air-Dielectric Sections

[Mike McCarthy]

Rigid line is rarely placed in an area which is not accessible to service 
the line.  As long as it's well supported and accessible, it can be used 
for long runs in any plane.  It's the line of choice for many interior runs 
which don't have room for large spools.
