Pete,
I am holding in my hand two manufacturs M17/128 RG-400 MR -C-17G 12814
Thermax RGS 400 and ALPHA MIL-C-17/1288 M17/128-RG 400
There Not supple stiff , not flexable like RG8X . The cable is STIFF
but can be bent in to a 2” dia loop. At 1 “ can be done but IMO not a good
practice.
The 8” in coil YIKES that’s stiff ?
YMMV

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.
