What are the differences between RG400 and LMR400?

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.
