This product is a short band LED light display SWR meter. Powered by RF tap power, no batteries needed, easy to carry. The SWR meter is a device that measures frequency signals using 5 LEDs to indicate the intensity of the signal and indicate the SWR range in different colors. 3 ~; Used to measure and display SWR of short-wave signals in a frequency range of 30MHz. The input power does not exceed 50W, and the minimum LED (>1.0 is equivalent to green light) requires 5W power and is suitable for a variety of shortwave applications.
Features:
Compact and lightweight, powered by RF tap power, no batteries needed, easy to carry, very suitable for amateur enthusiasts in the field
It can be used to measure frequency signals, use 5 LEDs to indicate the signal strength and different color LEDs to indicate different SWR range.
3 ~; Used to test SWR of short-wave signals in a frequency range of 30MHz. The input power does not exceed 50W, and the smallest LED (equivalent to green light >1.0) light requires 5W power, suitable for various short-wave applications.
This device is commonly used in communication systems such as radio broadcasting, TV broadcasting and communication.
This helps the operator judges the signal strength and adjusts the device settings to improve signal quality and reliability.
The entire circuit does not require any components to be adjusted and will work as long as it is properly connected. IN is RF input, OUT is RF output. The IN terminal connects to ANT, and OUT connects to the antenna.
It can be used in shortwave bands without calibration or adjustment, making it very easy and convenient for DIY enthusiasts.
