Mystery solved, at least part of it..
Don't know how many of you have seen this system, I noticed the unit
sitting on top of the landfill mounds under the flightpath to SDF in
Lousville KY Alongside I-65, just north of the Outer Loop.. I know it's a
radar unit, But it has two scanners/antennas one vertical and one
horizontal
Been trying to figured what it was, now I know.
And now which model, is the question..
It's a AIRCRAFT BIRDSTRIKE AVOIDANCE RADAR or
Avian Radar System

GMI MARS® bird detection system
