Re: Help with ethernet over TV antenna co-ax
Two years late but this may still help someone :)
Simple signal sharing the co-ax cable is a non starter for all sorts of electrical & signal reasons.
However, if it is it possible to run another length of co-ax outside this kit would do it. RG6 is better than RG58 for digital use, far more robust & cheap as chips compared to external rodent proof CAT6. The single co-ax wall faceplate can be replaced with a twin plate - lookup satellite faceplates online.
The only new holes you will need is one from behind the living room outlet to outside and one from the attic. (both aimed slightly downward heading out)
These kits used to be quite common when the old 50ohm thinwire ethernet was going away.
Best option is to put CAT6 in the walls just before you redecorate the house, you may get that past the planning commitee if you can come up with some other uses for the cables. (SmartTV, use of networked printers in attic, landline extension)
