A potential buyer of Passive Radar Scramblers should question the claims offered by Rocky Mountain Radar, the largest manufacturer of passive scramblers. When a claim is made about jamming to within 100 feet, (the "punch-through" distance where the radar gun power overpowers the jammer power of a Passive Scrambler), Rocky Mountain Radar should be able to prove it with written test reports and/or videos from Speed Measurement Labs (SML), the recognized authority in this field.

However, SML has shown a multitude of times, on video, that Passive Radar Scramblers are ineffective from two miles, 1 mile, 1/2 mile, all the way to the radar gun; so, how is it possible that a Passive Scrambler can provide the advertised 100 foot "punch-through" protection?
