Hi, it is tri shielded alluminium cable.
currently, hardly any Digital or Sky coax meets this spec.. as it is all dual shielded and lacks the 3rd layer as VM cable is manufactured for them specifically.
the only cable that does meet this spec, in fact exceeds it is
Webro HD100
which is, tri shielded copper cable
available in various lengths here.. this exceeds VM spec

Needs the PPC EX6 NT+ connectors though, which have the serrated nut.. this is the only ones VM use now.
PPC EX6 also works, but its a prior version of the connector NT+ version is an improved version
