My old analyzer was sufficient for a long time, but as I gained skills in building ham radio antennas I needed to upgrade my tools at a reasonable price. The other worked and told me the SWR was fine at a certain frequency, but didn't give me any data on how well it matched, impedance values, or let me test coax or anything along those lines. It's fantastic because she told me the other things I needed to know. and now I'm redesigning some antennas to make them even better. I should have gotten it first. The battery is not included so I use a small 12 volt battery to make it portable and a wall wart for dyno testing.
