SW-102 Digital VSWR Power Meter 125-525MHz

SW-102 Digital VHF/UHF VSWR Power Meter 125-525MHz

The SW-102 is a compact digital VHF/UHF VSWR and Power Meter with a built-in frequency counter. It is designed for amateur radio operators, radio technicians, and users of analog VHF/UHF transceivers. The device provides direct digital readout of forward power, reflected power, VSWR (Voltage Standing Wave Ratio), and transmit frequency without the need for calibration. Its low insertion loss allows permanent inline connection in the antenna system. It features a rechargeable Li-ion battery and a clear LCD display showing all key parameters.
