An interesting topic!
Do you use any analysers in your shack?
Maybe portable out in the field?
With such a large range of cost effective solutions for very person out there, these devices are a critical component to anybody’s home shack.
Building your own antenna? Use the analyser to fine tune your desired frequency to squeeze out that extra half an S point.
Suspect faulty coax or possible water ingress? You can perform a TDR test to identify the potential location of the fault.
So, What do you run in your shack / portable bag?
