Connect 2 boards using co-axial cable

Is it possible to connect 2 arduinos or arduino and a different board through a co-axial cable or any type of tv cable ? If so, can I also use the cable to carry power for other small electronics like a camera or small servo or dc motor ? I'm interested because I have a hydroponics project that I want to implement. Thank you !

A cable is required, but the required cable type depends on the transmitted signal(s). A coax cable works best with proper termination, drivers and receivers, otherwise it’s as good as any other shielded cable.

Delicate electronic circuits are required if signals and power shall be transimitted over the same wire. Otherwise cables with multiple distinct wires are much easier to use.
