About this item

• Feature: 1. No Power Supply: DIY digital power standing wave meter, small and portable, built in rechargeable battery, no external power supply. 2. Digital Display: SWR meter can directly display forward power, reflected power, antenna power, antenna efficiency, standing wave, battery voltage. 3. High Accuracy: Digital standing wave meter s accuracy meets the needs of amateurs, high standing wave, battery undervoltage buzzer alarm function. 4. Power Range: 0.5W‑120W (up to 200W, below 120W long term test recommended FM, AM, CW mode, SSB mode optional), one touch display, mode switching function. 5. With Indicator: Red light is displayed when charging under power on, green light is displayed when full, yellow light is displayed when undervoltage. Specification: Item Type: Standing Wave Meter Material: Aluminum Alloy Color: Black Battery: Polymer Lithium ion Battery 503450 (Built in) Capacity: 1000mAh Charging Interface: Type C Frequency Range: 1.8MHz-50MHz (Actually Has Reference Value for V band) Measurement Accuracy: <+-5percent Vswr Range: 1.0-99.99 Access Interface: SO239. Package List: 1 x Standing Wave Meter Note: The green light is on when VSWR is less than 1.5, the yellow light is on when VSWR is greater than 1.5 and less than 2.5, and the red light is on when VSWR is greater than 2.5. If the VSWR is greater than 2.5 less than 3, the buzzer will alarm intermittently, if the VSWR is greater than 3, (aisanray) will alarm continuously. Battery undervoltage, the buzzer will keep prompting and the yellow indicator light will be on. The buzzer can be turned off with one key
