By Johan Fuhri, Product Owner In the previous blog post we considered some of the ways in which we can express the performance of an DF antenna, and we noted that simply stating the ‘accuracy’ of a DF antenna is not quite that simple. We also noted that there are various algorithms that can be…

By Johan Fuhri, Product Owner Part 1: Accuracy and Sensitivity It is sometimes said that: “If you can’t convince them, confuse them!”. Nowhere is this more apparent than the minefield which is antenna datasheets and brochures. Direction finding antennas are meant to be instrumental in accurately determining the direction of an incoming signal, that much…
By Eugene Botha and Kalinka Faul Humans do audio direction finding to a remarkable precision of less than two degrees. Shortly after the development of radio transmitters and receivers, radio direction finding (RDF or just DF) evolved for much the same reasons as human audio direction finding: firstly, for the location of possible threats and…
