1.Understand the purpose of an SWR meter:An SWR (Standing Wave Ratio) meter is a device that measures the efficiency of your radio’s antenna system by indicating the ratio between transmitted power ...

In setting up transmission lines, it is often desirable to measure the amount of signal reflection. The relevant metric is the standing wave ratio (SWR). SWR is defined as the ratio between the ...

SWR or standing wave ratio is the ratio of the amplitude of a partial standing wave at an antinode (maximum) to the amplitude at an adjacent node (minimum), in an electrical transmission line. The SWR ...

The project was based on a PIC16F877A microcontroller for the basic purpose of encouraging radio amateurs to build their own SWR meter at a very cheap price compared to high-priced ready made. Two ...

High Performance HF Power meter using Arduino and a Directional Coupler This device can measure power over a wide dynamic range from 10uW to 1 KW and will derive SWR for a 50 Ohm load The front end ...

Even with the rise of cellular communications, radio networks remain an important part of business communications, especially for small businesses such as trucking and security companies. Proper ...
