Have to agree with beetle on that one,buying rg8 is suicidal,as he correctly says it was surpassed by rg213 as the US mil spec decades ago,anything called rg8 now will just be a cheap imitation of the original spec,probably cheaply made in china.

RG213 is now also being cheaply copied,especially here in Europe where real M17/74 is nigh on impossible to get.Buying that sort of crap just encourages them to make more of it,insist on the real deal QPL mil spec coax.

Be very wary when you see the word "type" printed on coax,it means this shit isn't real with the emphasis on the word SHIT.

Gee, having used RG-8 for more than 30 years, I guess I've just gotten used to it's shitty characteristics and don't expect any more from it than I do. I guess I can look forward to th same lessening in quality with RG-213, and...gasp, the LMR series of cables. Oh! Ain't it awful? The whole world is going to hell in a hand basket!

You can look forward to it happening to RG-213, LMR-xxx and other cables if/when the US military decides to eliminate it from their specifications.

I'm not saying that there isn't any decent quality RG8 out there. What I AM saying is that very little of the stuff that's marked "RG8" is in fact any good, and even less of the stuff that's marked "RG8 TYPE".

What does "RG8 TYPE" really mean? That depends on the manufacturer and how many liberties he took with the specifications for the cable you're spending good money on.
