• VSWR. Forward and reflected power direct digital readout, without any calibration. NOTE: DOES NOT compatible with Digital Radio.Build in Frequency country. Interface (in and out ): SO239
• The SW-102S Digital SWR Meter is engineered for optimal performance within the popular VHF (144-148MHz bands) and UHF (430-450MHz bands) amateur radio bands. This is where it delivers its most accurate readings for Standing Wave Ratio (SWR) and RF Power output, essential for setting up and maintaining efficient antenna systems.
• Low insertion loss (0.3 decibels or less) structure allows it to be permanently connected
• Handheld Radio Users Note:Many handheld radios have a low-power ("Low" or "Eco") mode that outputs BELOW 0.5 watts. If your meter isn't reading, first check that your radio is set to MEDIUM or HIGH power.
• Requires Minimum Power: For both the SWR and Power Meter functions to work accurately, the power meter needs a stable input signal of at least 0.5 watts. Maximum measurable power range up to 120W
