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.

I just bought 10 feet of RG-400U (supposedly Harbour Industries)
through E-bay for $13. Belatedly, I learned it was coming from
China. It's now here, but I don't think it is for real - it only has
one shield, and is somewhat stiff. At least the inner conductor isn't
magnetic.There's no printing on the cable.
Buyer beware.

I third the sugjestion of the RG400 small enough for all the switching in
a more then one radio setup.
The tight bend radius the small diameter make for a clean instlation that coupled
with the double shielding it’s a WIN WIN
Watch Ebay or other surplus suppliers

Keith:
A couple very similar candidate cables are RG-400 and RG-303. RG-400 is
double shielded while 303 is single. They're good as interconnects
because they have a small bend radius (about 1"). RG-400 uses
multi-strands of copper for the center conductor; RG-300 uses copper
clad steel. Either will handle 1500 watts at HF.

My multi-two station, with third spotting station, is being rebuilt into new
digs. I have a lot of 3-4 foot RG213 cables running between the amp, power
meter, tuner and switch. I have heard there may be a smaller cable that has
very little loss, but handles 1500 watts. I would appreciate any comments
on what is being used today. Thanks.
