There are Powerline adapters that run PowerLine over 75Ohm Coax cable (via F 
connectors). I briefly worked with some of them (Corinex) a while ago.
Original PowerLine is crappy, but running it over Coax works quite well. 
Still, the devices are Modems, need 10-15W and aren't cheap.

The nice thing is they usually work in Multi-Slave mode, so you can have a 
single Master on the roof and several Slaves on the same Coax Network, 
splitted via typical 3/6dB TV splitters.

If there's no way to run CAT cable, this is probably the next best thing.

Yes, original Ethernet was 10Base Coax, but with 50-Ohms impedance and only 
works in Line topology. Also, DOCSIS would be nice, but that's like running 
your own LTE infrastructure for your wireless babyphone ;)
