The Nissei DG-503 works in the 1.6 to 60 MHz and 125 to 525 MHz bands, measuring from 1 to 200 Watts with measurements displayed simultaneously on the large 3.5-inch backlit display - direct power, reflected power and VSWR of analog signals. The DG-503 is not intended for use with pulsed digital, DMR or SSB transmissions.
Features separate inputs and outputs with switch selectable SO-239 connectors for the 1.6 to 60MHz or 125 to 525MHz.
