As a race director, watching the scoring software, I get notifications of "weak" transponders reads. More times than not, these transponders are mounted either vertically or directly on the aluminum chassis. Moving them and mounting them horizontally solves the problem.
This doesn't mean it won't count (at all) mounted like this. Just FYI.
