I got 1.3 mile range at least from constant on MPH Enforcer, Ka Band (33.8). I turned left onto road and first alert from leo with constant on 4 lane highway (6 total lanes, 1lane is parking lane on each side)occurred at 1.3 mile distance as I completed my turn and ramped up nicely as i drove closer. Leo was on east bound traffic side pointing towards me while I was moving west bound. Road was fairly flat and traffic was medium. RD was set to Auto for in town use and is mounted low just above the windshield wipers.
