Modified 190B Tektronix constant-amplitude signal generator is combined with 50-ohm resistance bridge toglve stable high-accuracy instrument for measuring voltage standing-wave ratio as guide fortuning antennas Range iS 160 meters through 10 meters，Trim Rx so incident or forward voltage at position 1 of S1 equals reflected voltage at position 2. Article gives chart for finding VSWR. Step-by-step procedure for modifying signal generator is given.-D.Sander, Make Antenna Tuning a Joy, 73 Magazine, May 1978, p 134-136.
