Mt first attempt at making a dummy load was a miserable failure. I put it on a network analyzer and saw the inductive effects of a length of wire almost immediately (10 MHz. or so). By the time it got to 50 MHz it was heading for capacitor land on the Smith chart.why not use a dummy load (non inductive resistor) designed for the frequency? 437 mhz requires a bit more care to eliminate swr than at 1 mhz, and use your digital scope if the frequency response is enough to measure the rms voltage across the resistor? P=Esquared divided by R. or hind a local ham who has a watt meter.
