Martin, hi.

My answer is a bit digital, unfortunately. Keeping the Flarm GPS
aerial on top of the instrument panel coaming kept it within about 1
foot, or 30 cm, of the Volkslogger, which seemed to be too close.

Other than sticking it on the canopy, which I did not think a good
idea, the only other place was on the headrest which I suppose is 2 or
3 feet from the Volkslogger, and everything works okay when it is
there.

500mm might be far enough, I suppose, if Redbox is that similar to the
Swiss Flarm – which I don’t know. I also don’t know how
representative was my experience.


Hope that helps, but I guess not much!
