SWR meters are used to measure the standing wave ratio (SWR) in radio equipment. They are sometimes called VSWR meters, a reference to voltage standing wave ratio (VSWR). SWR is the ratio of 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 ...

Description: upgrade required) Note: All N8480 series power sensors are not compatible with the Keysight 43x, E1416A, N8262A power meters, 5314x microwave counters and E7495x base station test set.

Mostly unmodified, but to open it down from 28MHz to 26MHz. Model features inbuilt VSWR meter, power meter, modulation meter, 10kHz up/down on microphone, mounting bracket, accessory connector, ...

Wondering how to get the best performance out of your homebrew WiFi antennae? This homebuilt SWR meter will help you measure and match the impedance of your antennae with your source. A good match ...

You have probably heard the statement about standing wave ratio: “I changed the length of the transmission line and reduced the SWR.” Or the opposite statement, “I changed the length of the ...
