"Skin back how far on the ends of the coax?"

I suspect the idea was to make a quick coaxial fipole at each end of the
coax.

One removes 1/4-wave of the plastic jacket at each end. Then one
carefully pulls the coax metal braid back over the remaining jacket as
far as it will go. You now have a coax 1/2-wave center-fed dipole at the
end of the coax where completed.

With a 1/2-wave dipole in a high-signal area directly connected to a
1/2-wave antenna in a low-signal area, energy is transferred from high
to low. Try it. It is cheap and it may work.
