There is a lightning detection system based on a group of enthusiasts. Detailed information you can find at

www.blitzortung.org

I own such a system too and therefore I am also part of this network. www.lightningmaps.org

My setup consists of an E-field antenna and a H-field antenna.

Living in a city I didn’t expect results over the average. But surprised I am very often in the top range.

Here you can see the stroke ratio of my station “Wien Mauer JN88DD45at”

Most of the time I am in the top 10. But sometime my station is detecting most strokes of all stations.
