Description:

N1201SA series is the handheld radio frequency vector impedance measurement analysis instrument, easy to use, simple operation. Built-in high capacity lithium ion battery for mobile and outdoor use.
Shutdown automatically save settings parameter without human intervention, after starting up, interface settings completely the same as the power off before, use very worry.
Can be used to test the antenna, the imppedance of the radio frequency devices.
As RF impedance measuring need calibration, so you need to purchae separately calibration.

Optimizing Antennas using a cheap N1201SA VNA (Vector Impedance Analyzer), LoRa, Review

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

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
