The APeX Clip was born as a solution to a problem. My fire department received new radios and there was nowhere to clip the mic on. The old radios had a much thinner antenna and we were able to clip the mics onto it. That was also a poor solution because it would end up destroying the antennas. The APeX Clip is the solution to have a place to clip the mic without using (or destroying) the antenna.
The creator of the APeX Clip, Peter Mills, has been a firefighter in Doylestown, PA since 1998. Here is a picture of him looking busy (Note: Picture taken before the fame and success of APeX Clip. Look at that mic!!!)
