Thanks aldoir, good idea to create new thread dedicated to Analyzer N1201SA.
Amazing to see this $140 analyzer gives same results as a $25,000 ~ $35,000 analyzer gave.
I have already discussed about NA1201SA, and posted test results for different antennas in following threads:
Off Designed-Frequency Behavior of 2 Types of Antennas
measuring antenna performance?
Waiting for others to post their test results in this new thread created by aldoir.
