Hey all. I'm a cable guy from way back and now I switched to power. I'm pretty good at calling out wire sizes by site for cable(rg-6, 11, fiber) and am pretty good at calling out power (2/0, 477kcmil, etc.), but I really don't have a good take on aerial phone. I can pretty much call out 900pr(cuz it's the thickest one I've seen). Is there a good manual/book for identifying cable just by sight.

Any help is appreciated.
