It sounds like you are trying to determine system gain and distance which depend on transmitter power, distance, cable/connector loss, antenna gains on both ends, frequency and receiver sensitivity.
I have a simple spreadsheet and perl script called pathcalc up on my site at http://www.lns.com/papers/patchcalc that will calculate this for you.
