Clarification for other readers. The center of RG142 is silver coated 
copper coated steel, the center of RG400 is stranded silver-coated 
copper. Both have double silver-coated copper braid shields.

Loss is about the same as RG58 -- in other words, fairly high. The 
principal virtue of these cables is their superior SHIELDING, which is a 
LOT better than most braided coax.  You only want to use this stuff for 
short jumpers.

I've been happy with at least two purchases of Harbour Industries RG400 
that I've found on ebay from a US vendor.  Harbour Industries is based 
in VT, and has a presence across the border in QC. NA6O was happy with 
the RG400 he bought from China.
