For example, you can have an exactly resonant antenna, which simply has the wrong magnitude of impedance (you need an impedance transformer). I've not personally built antennas from scratch, but I appreciate my antenna analyzer just for being a good instrument - making the invisible aspects of my antenna system visible.Ĭompared to using a SWR meter for the purpose, an antenna analyzer:Ī SWR meter still gives you enough information, in the sense that you can try things until they move towards 1:1 SWR, but it's a one-dimensional measurement: if you tried to adjust an antenna using it you're doing a “hotter colder” search, trying things until it improves.Īn antenna analyzer will tell you resistance and reactance independently, which allows you to more directly understand the problem.
