Setting up your own sensor is easy and cheap. You only need a simple single-board computer, an SDR dongle and an antenna. We have tested several computers and antennas and provide you with our recommended setup below.


The right antenna for your setup depends on the frequency range you are interested in and if you want to measure in- or outdoors. Here is a table of antennas that we use in different setups with their respective properties, advantages and disadvantages. If you are using other antennas, feel free to send us your hardware setup so we can continuously extend this list.
