Active countermeasures provide the highest protection possible.
We do not manufacture low performance passive scramblers, which have not yet passed a highway performance test conducted by Speed Measurement Labs. SML is the test standard that everybody has to meet, before you sell a product. If a product can't meet the tough performance criteria of an SML test, you should not consider the product for a purchase. We provide our SML test results under each product category. We provide SML video results for you to review our product performance.
