The impedance of a power line varies a lot with frequency.  Power
couplers use capacitors and transformers to try to match the impedance
the best they can, but it's hard to get anything broadband.

Then there are all the safety issues when dealing with high voltage,
and the protection circuitry for the 50-ohm side to deal with things
like lightning induced spikes, etc.
