True enough George and an old practice to be sure. The key, as you point out
is to have short runs where the losses were acceptable. The writer of the
original post mentioned using two coaxial lines for the ENTIRE RUN of
feedline from the antenna to the rig! That was what I was commenting on. In
that case, if the shields are used to prevent radiation, one would expect
the same sort of losses that any long coaxial cable run at high SWR's would
produce.
