JAB, you must have missed a couple threads on this subject:
Basically how it would work is like this:
A Dot Dar radar would be effective at 25 miles, ie, no matter WHAT alt you are at, you'd show up on the dot dar. The bar dar just allows you to go from point A to point B by taking an indirect route around neighboring fields, as to not give yourself away...as soon as you start to stray near a field to attack it, you are detected 25 miles out from Dot Dar. Not only is the offensive low, but very vulnerable. And the defender has plenty of time to get up and defend their field as well.
