thanks Marc, er....I did know all that though & my question was about the d=
ifferences between aluminium & copper shields.
50 - 100m cables are generally what I want to keep on hand due to the way I=
work.
Canare- sorry Marc, I assume of course that you mean its been your 'cable o=
f choice'. It's no more the unquestioned cable of choice than a large numbe=
r of other cables.
