It's a little smaller in diameter than 6.<br /><br /> IIRC, RG-6 and relatives are made in both solid and foam core (plus some nasty weatherproof versions with sticky gunk under the outer jacket and a version with a molded-in steel carrier wire that will ruin diagonal cutters). You shouldn't step on or sharply bend any of the flexible cables but the older solid-core stuff has a relatively stiff, incompressible translucent dielectric that is fairly rugged. Foam core has a white, compressible closed-cell foam dielectric. In the latter, the solid center conductor can migrate through the foam if it is sharply bent and it is a lot easier to smash. You can check scraps of your cable and tell what kind it is.<br /><br /> Baseband digital video is generally less tolerant of cable faults than *any* kind of RF: my stuff breaks easier.<br />Roberta Xhttps://www.blogger.com/profile/09956807794520627885noreply@blogger.comtag:blogger.com,1999:blog-5837660608809488753.post-4241677455824724162015-10-25T08:03:01.476-04:002015-10-25T08:03:01.476-04:00Hi Roberta,

Is RG-6 the foam dielectric fiddly stuff you're referring to? Or is that a property separate from the cable type to look out for and treat gently?

I started tracing from what I thought was the source, only to discover it came from somewhere completely else, so I had to start over, at the destination, and work painfully backwards. To begin with, I didn't even have a portable video monitor, and this signal was in three different flavors, depending on where in the chain of converters one was looking.
