RG-400 is another PTFE variant, being similar to RG-142. Tooling dimensions
are identical to RG-58 and RG-142; crimping and stripping tools designed for
RG-58 work well with either RG-142 or RG-400.
I'm now using RG-400 for all inside shack coaxial cabling, including
post-amplifiers. Outside, the cabling transitions into either LMR400 or
600-ohm open line on ceramic spreaders. With RG-400, I opted for slightly
more loss in the shack with relatively short cable runs, but the benefit is
in having bundled cables that take up a fraction of LMR/RG-213 types.
