Yes, really. You measure the forward power, then turn the element around and measure the reflected power. Then use 10 log (FP/RP) and you have the return loss in dB.

Oh really???!??!? The Eagle return loss bridges are a good value for the buck. www.eagle-1st.com. They have a whitepaper on tuning duplexers too. http://www.eagle-1st.com/notes/duplex/body.htm I believe IFR (now Aeroflex) sells (or at least sold) the Eagle RLB's. --- Jeff Yahoo!
