SWR meter - A DIY project
It's been a while since I made a tutorial so I figured it's time for another one. This is my DIY SWR meter. The complete build and operation instructions can be found here: http://fpvlab.com/forums/showthread....urself-project
It is made of 5 parts:
Microwave detector diode
Short RG316 jumper
You must be a master at soldering to build this, but it's cheap and works all the way up through 5.8GHz. That's right, a 5.8GHz SWR meter. Finally!
SWR is calculated as follows:
p = Vr/Vf
SWR = 1+p/1-p
Videos of how to use it:
Good luck and have fun with this one.
