jetvision LR-1090-N - a 1.5m long
AntennaFor a long time I used the G7RGQ
and afterwards the collinear stacked from Francois, F5ANN. Suddenly
Andy presented me a 1.5m long stacked vertical antenna, and after
testing it, I found this antenna giving me about 25nm more range, to a
total of 225nm into all directions. See the proof below.
am happy that the constructor took some of my hints and experience into
his design, and Andy soon will offer this antenna in his web shop.

wonderful antenna - mounted on a sidebar at my rooftop
My current range with this antenna is more than 225nm into all
directions that are not shadowed by mountains. To the south you will
find the alps as a barrier, towards west the Schwäbische Alp
moutains show a limit. All other direction are free. The typical Mode-S
frame rate during busy time in the evening is 1200 frames per second
