Klaus owned a fullsize 3 ele quad for 80m with a 5ele 40m quad interlaced.
In January 2018 the tower with antenna crashed during Storm “Friederike”
The antenna (200.000€+ since 1990) was 80m high at the upper spreader tips and weighted 1,7tons. Built in 1990 it survived plenty of storms.
Klaus was a great guy sharing his knowledge about quads and was active in contesting and DXing….
