Well, it receives better than the 436HP, however, reception is still sporadic. Michigan State Police reception is sporadic as well. Some police dispatch districts are not coming in at all. I'm using a Diamond 800mhz rubber antenna. I'm in Royal Oak, 2 miles north of Detroit City limits. I intend to drive into the city to find out if reception improves. Detroit Fire, EMS, sporadic. The audio volume seems very good. Detroit reception on the 436HP was barely usable !! So there is an improvement.
