I caught a YouTube video on these and I am very interesting in getting one for my shack however I know next to nothing about them. I have several antenna analyzers for my ham radio equipment and these look like they could be an interesting tool. I have looked on Amazon and there are a number of these with different names and models. They range in price from $35 to $80. How do I determine which ones are good and which are bad?
My Youtube channel is hamrad88 and my name is Tom Stiles
Thanks for your time.
