I love this device. Sole people say they are too small. But they must have gotten the smaller version. It does more than I know how to do. I use mostly to test antenna SWR and it works great for that. I wish I knew more about the other functions as I know it can do a ton of stuff. It’s great to run a wide sweep of an antenna. It actually helped me finally determine a mobile antenna was bad. Not that mount as I previously thought.
