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.
