Knowing how your antennas work or build and optimize our antenna is very rewarding. Unfortunately, it needs know-how and some costly equipment to do that. Today we will change that, and I show you an affordable new tool that enables these tasks. This small device was one of my best investments I made so far.

My HAM Radio channel:    / @hb9bla  

At the end
- You know how to build and optimize a LoRa ground plane antenna
- You will know How to tune a commercially available antenna
- You will get a little theory behind it, as usual
And we will have a close look at this small gadget from China and compare it with a professional tester
