Wi-Fi SWR Meter
When building antennas for the Wifi band Like the 8dBi omni, a need for an easy way to check the antennas arose

WiFi SWR Meter
Misuratore di VSWR per le VHF-UHF-SHF, 2m, 70cm e 13cm delle bande Radio Amatori

Homebrew pwr-swr meter
xperiments with a tandem style swr coupler. the coupler uses two ft50-37 toroid cores, each with 10t

A little about SWR
No discussion about antennas would be complete without a word or two about SWR

A PIC16F876 based, automatic 1.8 - 60 MHz SWR/WATTmeter
The reading is quite precise in the whole HF band, up to 50 MHz, covering the power range from 5 to 120 W, therefore usable also in the QRP range
