Good idea ;-) But it was dark so i didn't find a target. And as i have been on the roof, 5 minutes ago, i installed it on the spark gap. Between the 7 and F of my QRSS-120 transmission;-) Now arcing is history!

Seems i need some improvements on the spark gap of my LF antenna. Depending on the humidity and wind there is some arcing during the transmissions. These look very fascinating i find. Anyway i have to add a spherical electrode there and increase the gap distance, especially for VLF ;-)

A working colleague of me is a (semi) proffessional photographer (hobby) and i asked him to take some nice pictures. He has an excellent equipment i find but he means he should have taken a different lens for these pictures. Anyway, i really like them. When arcing at the ends of a LF antenna is discussed, sometimes a picture can help a newcomer what is meant. Here are some more examples, in high resolution (abt. 3 MB each)
