Right. Hardline, whether corrugated or smooth wall, is usually specified 
at 10 times diameter = minimum bend radius.

BTW, RG-8 is really 3/8" coax, so if 6xD is the spec, it should be OK 
wound on a 4.5" coil form for example. I would be concerned though about 
foam dielectric RG8 though on that small of a form.
