I think that if Flarm were installed with 2 antennae, one high in the
cockpit or on top of the fuselage, and the other below, there would be
no Flarm blind spot and it would be as near perfect as possible. We
don’t do that because it is too much trouble and/or too expensive. It
is hard enough to persuade many pilots to have Flarm even in its most
basic available form.

That's what I decided on last winter., because the Flarm range
analysis on my carbon fuselage Flarm installation (Ventius cM) showed
that there were some blind spot (ranges 2km). I installed an antenna
splitter, the original Flarm antenna outside the fuselage near the
gear doors, and a stripe antenna behind my head inside the canopy.
"Blind spot" now means a range of 4 km ( a bit more than 2 nautical
miles for the colonials).
Investment was $200. My ass is worth more than that.
