This is what an experienced ham K0UA says about our device,
“I didn’t know what I was missing!I have been a ham for almost 50 years, and I have learned more in the last couple weeks of owning the AA-55-Zoom about my antennas than all that previous time. It is also useful for checking Ferrites, coax quality and many other things. It is so easy to use, you don’t really need the manual. Plus it has built in help if you get lost. Truly a wonderful tool and worth every penny.”
