Pete,
Checked some RG142 vs RG400. With a hand squeeze test it is easier to flex the
RG400. Not scientific but you can feel the difference.
My RG400 is marked "M17/128 RG400 MIL DTL 17 27478 HARBOUR INDUSTRIES".
It is tinned double shielded braid with a stranded tinned center conductor.
Nothing attracts to a magnet. It is easy to make a 2" coil. But it will spring
back if you let it go.
I did buy some RG179 on ebay. There are no markings on it. So somewhat
concerned. It does seem to check out fine. But?? Will be buying Harbour marked
coax so less doubt. Some folks on eBay are selling "HARBOR" coax. 😊
73,
N2TK, Tony

Oops. I did some more dissecting on the cable, and I'm wrong about the
shielding. That leaves only the absence of printing - this is advertised as
Harbour Industries RG-400 - and its stiffness. This stuff is quite hard to
bend in even an 8" coil. Can anyone who has used real RG-400 confirm whether
it feels supple and flexible to the touch? I have one jumper in my station
that looks like the same stuff, but which is very supple. I bought it at
Dayton a few years aho, already connectorized. I can believe a 1" minimum bend
radius with it, but not with the stuff from China.
