Not sure if this is kind of unusual (may be it is for CA), I noticed one of the local PD uses Ka-band. It should be rear facing since the duration is longer as I'm approaching from behind the source.
The signal spans about .3 mile and the source is at the end of a turn. That's a pretty nice save if you ask me. One question though. What's the easiest way to identify if the source has one two antennas? As I'm getting closer, the bogey goes to 2 and I'm not sure if the OP is shooting the other side of the street also. But goes to 1 when I'm pretty much next to the OP.
