In the admittedly very few looks I've had at mobile "shootout" results,
there seems to be more of a correlation between vehicle size and field
strength than antenna and field strength. This comes as no surprise,
since the vehicle is usually a comparable or even greater part of the
radiating system than the titular antenna, and its coupling to ground
has a large impact on the efficiency.

Which is why, in this case, it is well to note that the 0 dB top-rated
antenna and the -12 dB antenna were mounted on the same vehicle
(mine).
