Lightning detection with a GPS synced radio receiver...
I have always had a very special place for lightning.
One can merely look at my flickr photostream and gather as much.
Strangely I live in the moist lightning devoid area on the planet...
So in the name of science, In November of 2020 I decided to buy a System Blue.
Essentially a lightning detector that is GPS timed synchronized with other detectors on a network and that uses the principles of Time of arrival TDOA to determine where a Radio Frequency event to place, in this case lightning...
Here is a live map of this network in action.
That would look something like this...
There is the antenna kit version that is for sale and I opted for the self build option and this kit comes at a price of 270 EUR. . .
I decided to build this as the first test antenna.
This is the first antenna a 100cm mobius coax antenna.
I decided to take what timber I had, which turned out to be 3x70cm pieces, and constructed a cross firstly, added some hooks.
I did some calculations based on the information I could gather on these loop antennas from the blitzortung forums.
I then spun three loops with 10 turns each having a diameter of 0.48m
I then proceeded to setup this device according to the correct guidelines as best as possible.
The E-Field antenna is a length of wire(~1000mm) stung up in a tree with rope and contained within 50mm PVC housing.
Here is one of my first hits with all four channels.
My live data can be tracked at Blitz, although I will admit that this system needs a serious upgrade...
