Default Co-as cable: truth or nonsense?

Quotes from a recent CCTV trade flier:

Start quotes

A solid copper centre core as copper is better conductor of electricity
and signals than gold! So go for copper conductors. Aluminium is only
61% as effective as copper.

Cheap cable such as CCA (Copper Clad Aluminium) and CCS (Copper Clad
Steel) - Cheaper but in reality a false economy. CCA is around 61%
effective as pure copper and CCS as low as 17% - In layman's terms; If a
copper cable works at 100m then the CCA would only work at 61m and the
CCS at just 17m !!

End quotes

Bear in mind that this is for CCTV, not RF. Since cable TV companies
often use steel cored coax for UHF I find the claims above surprising.
