RF transmission

Would it be possible to connect the antennas of two SIP/Dual-mode tranceivers to allow for bi-directional communication between two stamps through a wire as opposed to just over air?
I ask because i have an ROV and for the tether i can transmit RF control signals down a coax and RF video up the same coax but i need to transform the serial from the stamp to RF for this to work.

I suspect if the appropriate coax were used which matched with the characteristics of the tranceivers that you are planning to use, it might be doable. This seems a long and expensive way to solve this problem.
Aren't there two other wires, other than coax, that could be used for communication? Couldn't you add a small, waterproof cable with two (or more) conductors in it, and afix it to the outside of the existing tether? At best you're only talking about half-duplex communication here, due to the inherent limitations of SERIN/SEROUT and the lack of a communications buffer.

in the past i have simply used a seperate wire for serial communication, but in the search for a smaller, thinner tether i stumbled across a design that runs an RF signal down a coax and video up the same cable. The RF signal used was from an RC system. This is the first time i have seen a way to translate serial into RF to work with this method of tether. Unless there is a cheaper way to send information between stamps using RF. If worse comes to worse i would end up just using more wires but that increases the size of the tether and i dont want to do that.
