How do I make a coax bridge over a network?

-This is an odd situation and I am not sure there is a solution out there but I thought I would try. I have a satellite dish that I need to connect to a device in another house. This isn't related to satellite tv but rather data. Is there hardware available that can transmit a coax connection over a network to create a bridge? I have seen similar devices for a serial connection in which a device encodes the signal and transmits it over a network to a receiving device that decodes the signal. I need to do this but just with a coax connection. Any help would be most appreciated. Thanks
