SWR Meter for 140-440 MHz
Recently, someone asked me about a VHF SWR meter, which I built over a decade ago from widely available parts

VSWR Conversion Table
The signal reflected back in a transmission line. vswr is defined as the ratio of the maximum to minimum voltage on a loss-less transmission line

SWR Power meter with protection for Solid State PA
Some people who built the power meter came with some good ideas and these were used for the Version II of the SWR Power meter
Wideband SWR meter
Among these instruments, the best-known and most-used one is the Standing Wave Ratio meter

Linear loaded short dipole 21Mhz For my amateur radio activities on the HF bands I only have a 3.6 m wide balcony available for antennas. After some study I decided to experiment with a shortened dipole for the 15 m band
Rx antennas 4Square Rx Vertical Array My frequency design of 1.825 MHz a 90 degrees line would be 33,70 metersinstead of the previously calculated 33,27 m
A simple SWR Meter is to be used at HF An SWR meter provides information about how well matched is your antenna with the transmitter and how well power is being radiated
