Is there an RCA to Coax Adapter? - coax to rca adapter

Hello. I want to a TV with Satellite Dish Network 2 tuners to install the second goes to another TV. However, only access 1 coax, 1 cat, 5, 1 have fiber between the two TVs. The receiver requires an RCA cable from the receiver to the TV seconds. Is there a way to covert RCA output of the receiver with a coaxial cable, Cat 5 or Fiber? I know there must be something there, I just do not know what it is. Please help!
