if you get coax from a satellite company it will be copper. if you get coax from a cable company it will be copper clad steel. has to do with how the system works.

Satcom stuff is very low signal strength. The LNB on the dish does nothing to boost the signal but it does strip out the carrier wave so all the receiver gets is the band the signal is on. (satellites pass down MANY MANY bands of signals) it's more technical than that but the idea is because signal strenth is so low they use high quality coax whereas the cable company has the option of turning up the gain at every node if you get crappy signal strength (the box cutting in and out and artifacting pixels)

Use a magnet to check!
I do it with all the coaxial I get. Oddly enough most of what I get is actually copper, an not that crappy steel/copper kind.
