We use the UNAT-30+ from Mini-Circuits (usually 3 stacked together) to test "bad" radios that come back, or for PtPs before we send them out. It has been helpful for tuning/benchmarking MikroTik wirelsss settings in a closed environment. http://www.minicircuits.com/cgi-bin/modelsearch?model=UNAT-3

The receiver impedance should match the cable impedance (50 ohms) for best receiver performance which the manufacturers are all trying to get. Also if the cable has enough attenuation to not burn up the receiver at the far end then even if there is a mismatch at the receiver on the far end the
