Cheapest 5.8g VSWR Meter (for FPV antenna)

Hello, I present to you the cheapest 5.8g VSWR meter for measuring your FPV antennas. Although it's a far cry from an Anritsu/ Agilent VNA, it gives the best accuracy for the buck!

A couple years back, I built an analog vswr meter using an old school multi-meter. While that works great as a tool for tuning my DIY FPV antennas (on my youtube channel), having to read the needle off a self-conjured swr scale (printed on paper) is not ideal for accuracy. Thus, I made this to achieve better accura
