I have reservations about the adequacy of copper cladding on the
cable such as yours at the lower end of HF.

I have often wondered the same thing. Mainly does the LMR400 center
conductor have enough copper over the center conductor for 1.8 to 7
MHz. I don't use it at all as I just don't like the cladded cable.




The issue is greater with the CCS conductors in ladder line, because the
strands are thinner in the first place, and the core is steel.

The effect of CCS inner conductor in some types of RG6 shows up as a
departure from the classic loss model at frequencies below 5MHz.
