Good luck with your favorite purchasesLED SWR Meter 3-30MHz Frequency Shortwave Standing Waves Indicator for Television Broadcasting

Feature: 1. Compact and lightweight, powered by RF-tapped power, with no batteries required, and easy to carry, very suitable for amateur radio enthusiasts to use in the field. 2. It can be used to measure radio frequency signals, it uses 5 LEDs to indicate the strength of the signal, with different colors of LEDs to indicate different SWR ranges. 3. It is used to test the SWR of shortwave radio signals in the frequency ranges of 3-30MHz. The input power does not exceed 100W, and the smallest LED (\u003e1.0 corresponding to the green light) light requires 5W power, suitable for various shortwave radio equipment. 4. This equipment is commonly used in radio communication systems such as radio broadcasting, television broadcasting, and radio communication. 5. It helps the operator to determine the strength of the signal and thus adjust the settings of the radio equipment, to improve the quality and reliability of the signal. 6. The entire circuit has no component that need to be adjusted and will work properly as long as the connections are correctly. IN is the RF input and OUT is the RF output. The IN terminal connects to the radio ANT and the OUT connects to the antenna. 7. It can be used without any calibration and adjustment in the shortwave ranges, which is very simple and convenient for the DIY hobbyist.  Specification: This product is a short band LED light indicating SWR meter.
