I don't know how many hams know about these now affordable testing devices. One is a spectrum analyzer and the other one is a vector network analyzer, both very expensive! Check the TinySA and the NanoVNA on EBay!! Both can be found for around $50!!!! Not thousands and there are lots of UTube tutorials on how to use these.
Now hams can afford these devices!!

The $50 NanoVNA's are not quality units. Supported devices that are well built with metal cases and 4.3" screens will cost around $100-$125. Still inexpensive compared to lab quality equipment. They can do a lot more than just analyze antennas.
Installing NanoSaver software on you PC is also a big plus.
Stay away from the AliExpress "specials"

Here's one application of a tinySA:

Those devices are just fine for amateur work, assuming you get one from a reliable source, and you are not planning on bidding on government contracts.
Check the groups.io forums on tinySA and nanovna-users for advice. I got both from R&L Electronics.
