I have hooked a loop antenna to the SCU-A RF Input.  I was wondering if SCU-A RX Loop output can be used to feed another receiver?  What is te purpose of SCU-A RX Loop output?

Love the ability to simultaneously receive on one antenna while I am transmitting on another.  It is extremely useful.

    It is like and effects loop in a PA.... You can loop your antenna out to a preamp, bandpass, or notch filter,  then back into the RXA input.  That way the filter is always out of the TX power amp line and safe from damage.

    If you don't use the Loop, then you can simply connect a receive only antenna to the RXA input.

    So will this do feedback for adaptive predistortion? That was my guess.

    Ahh.  Got it.  Guess it won't do what I want to do, oh well.

    Like the idea able to receive while transmitting.  Very useful.

    Thanks for you explanation.

    The full-duplex mode allows transmitting and receiving simultaneously. Check the manual for the details. I use it frequently for satellite work.
