Hello Paul
Yes, DXE cables (with UG adapters) are made using this ultra-superior
method. The UG adapter is silver plated so it makes it even easier to solder
the shield this way.

Tim,
Since RG-400 requires a UG reducer with a male PL-259 UHF connector, DXE may
want to consider this ultra-superior method of connector installation when
fabricating cable for its customers:
https://www.dxzone.com/qsy12138-install-a-pl-259-on-an-rg-8x
Although I now prefer crimped connectors for inside installation, the method
linked above is far better than anything I've tried. Everyone I know who
has tried it has never gone back old installation methods. There's complete
control over the entire process with the ability to fully inspect the
connector as the barrel is screwed onto the reducer. That's difficult with
the age-old "Amphenol Method."
Paul, W9AC

For those that do not want to build their own, DX Engineering makes various
lengths of jumpers using RG400 with Amphenol 83-1SP UHF male connectors
(very high quality)on both ends. Hi pot tested and silver soldered - ready
to go.
The double shield with RG400 works great.
The K3LR station (11 operating positions) uses all RG400 jumpers.

Real M17/128-RG400 spec RG400
There are a bunch of "RG400"ish cables our there, so I only buy known maker
with milspec id on jacket.
I have about 100feet of Harbor M17/128-RG400 around, from 3 or 4 diff
sources. I use for "choke in box", test leads, rotator loops for 6M and
down, etc.
Spent forever searching, but ended up settling on milspec RG400, and I found
some UT-141 milspec cable that is raw copper shield, with silver plated
copper center instead of SCCS. (There seem to be about 40 sub-versions of
UT141, 3 or 4 have a silver plated copper center instead of SCCS).
Above 6M for rotator loops and similar I like M17/127-RG393, but hard to
find at a reasonable price.
Suggest hitting the auctions and specifically looking for M17/128-RG400
where you can clearly see Harbor Industries and M17/128-RG400 on the jacket,
took some shopping but I don't think I paid more than $1/foot for the
several hundred feet I purchased over the last few years, just had to watch
and wait for a decent deal on a 30+ft length.
If you only need a few feed once, it is always around in 10 - 20ft lengths
for several times that.
