I just purchased this unit from radarbusters and I have a few questions about it... First of all, how long will the heads continue to jam? I mean if I am driving through a speed trap assuming that the blinder is able to JTG am I limited to a time window before the heads have to recharge or anything like that? Second, I was considering the mounting position shown in the picture below do you have any suggestions in terms of improving this setup? I was also wondering weather or not the heads cause interference when spaced to closely together? Thank you for your help.
