The key is to find RG6 that is swept to at least 3GHz. Satellite systems
(like Wildblue and Hughes) send at least 30 volts down the coax to the TRIA
(transmitter receiver.) For long runs CC steel does not cut it and these
coaxes all have a solid center conductor. If you dig a bit deepeer you can
also find direct burial grade RG6 that are flooded with a substance that
inhibits water ingress if the cable is nicked or scored.
I get mine from a Satellite TV distributor
