What is nice is that you can run it by computer and save the plots. I did a sweep of all of my antennas and have saved them, so if I think something has changed I can compare with the older information.
There are a lot of youtube videos on all of things you can do with it. There are two groups on groups.io that also have lots of information.
Jerry glad to hear the ice is off the antenna, a problem we don't have in FL, hi hi. Hope you get the remote switch fixed.
