The underground build cost is what left the cable networks in this sorry state in the first place. The document I linked to earlier in this thread highlighted the fact that this takes 70+% of the capital investment, leaving less to be invested in the technology. Thus IMHO compared to Sky who lease a Sat, space and invest in the technology platform cable is going to struggle to keep up until the infrastructure build cost becomes a legacy issue (as it effectivly is for BT).

Fibre is available (was a few years ago anyway) with a strain wire fixed to the jacket for enable it to be strung overhead/between poles. fibre between poles would be far more reliable than coax/RF as fibre is not as easily broken by flexing as coax, and does not corrode due to moisture ingress that causes frequency response and high resistance contacts on connectors/joints.
Fibre does not suffer from EMC ingress/egress either, nor does it suffer from moisture ingress like coax does as mentioned above.
