A very incorrect statement.

CATV foil is bonded to the foam dielectric, it doesnt "crinkle" as with 
audiophool stuff.

The better CATV cables are Quad shielded. I use 75 Ohm cable throughout my 
station from 1.8 MHz to 1296 MHz. From RG-6 up to 1" hardline. Lower loss 
than equivalent size 50 Ohm cables.
