Arduino RF power & SWR meter


My primary interest was for VHF/UHF/SHF, I have foreseen positions for 6m, 4m, 2m, 70 cm, 23cm and 13cm bands - but you can use the ARDUINO readout on HF as well

A Mini Primer on SWR Measurements
Every radio ham needs an SWR meter. Even though comercial rigs have builtin digital readout SWR meters

A Small Digital QRP SWR Meter with OLED Display
Most accept that transmitters operate best when the power output is connected to a load which presents an SWR below 2:1. For example, 100 ohms, 25 ohms

Antenna Reflection and SWR Calculator
VSWR return loss and reflection coefficient, which are different ways to express how well a load is matched to a source

Linear-loaded-short-dipole-21mhz

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
