If the duplexer is correctly tuned, there will be NO measurable SWR into it. If you have 25/60 watts, it is way off frequency.

I have a DB products 2 meter duplexer on an amateur repeater. Measuring with a Bird wattmeter between the duplexer and antenna I read 50W forward and a couple watts reverse. That is ok. But when I check between the transmitter and the TX port on the duplexer I get a about 60 W forward and 25W reverse power. Is there a rule fo thumb for a known good SWR value thru a duplexer? Should a good duplexer introduce any significant SWR? Thanks Bernie Parker K5BP
