Sorry, I was not clear. 
Right now in AH there is a world's eye view radar that allows people to see beyond the range of base radar.  What I am suggesting is that we limit the radar in game to only base radar.
Which gives me another idea:  radar bases.  These bases would not have anything really at them other than a radar tower and some flak to defend.  There purpose would not be to produce radar, but to serve the same purpose as the world-wide uber radar does now.
