With the % of people using RD I’m surprised they cared that muchKa has a narrower cone. Also, when Ka was new the cops probably thought it was slick to have a radar system that millions of existing RDs couldn't detect. In those times Ka was harder to detect even by the new RDs that had the capability.
There were many more people using RDs back in the late '80s/early '90s. @CarefulDriver is correct- Ka band's higher frequency allowed for substantially smaller antennas. Stalker Ka has greater range and much better same lane performance that the old Kustom K bands that were capable of same lane.With the % of people using RD I’m surprised they cared that much
Just to expand on this a little...I have understood that frequency has something to do with antenna size. Higher frequency, smaller antenna.
I recall for YEARS past the NYSP going 100% ka Stalkers seeing OG Passports and Escorts on people's dashboards
