NISSEI DG-503 MAX
DIGITAL SWR/WATT METER FOR DMR (TDMA), SSB (PeP) AM, FM, CW, FDMA - DUAL SENSOR: 1.6-60 and 125-525 MHz - 200 W
The NISSEI DG-503 MAX is a high-quality digital SWR and Watt meter for accurate measurement of forward power, reflected power, and VSWR. Developed based on the DG-503, the MAX version implements the same functionalities with the addition of DMR, SSB (P.e.P.), and AM power readings, selectable via a switch on the back.
The NISSEI DG503 MAX has a frequency range of 1.6 to 60 MHz (VHF) and 125 to 525 MHz (UHF), and a power range of 0 to 200 Watts.
The NISSEI DG-503 MAX has 1 UHF-female input connector and 1 UHF-female output connector for each band: HF/VHF (1.6 to 60 MHz) and VHF/UHF (125 to 525 MHz).
The voltage of the NISSEI DG-503 is 12/13.8 Volts.
Main features:
1. Large 3.5" LCD display for immediate reading.
