I have done this for all SO-50 passes because I want to hear my own
downlink (and record the results with a voice recorder from the downlink
HT earphone out) but I didn't notice any discernible difference without
the duplexer because I'm only running 5W. (Antenna is handheld.)

Arrow Antennas states that max power for the Alaskan Arrow (the type I
own) without the duplexer on a tripod is 150W. (See FAQ at http://www.arrowantennas.com/arrowii/alaskanarrow.html)
