Yes I understand some are using higher voltage than 18V, like 24V, and is working fine and that is the maximum limit I will say. However, we have to tell you the specification from sB is 18V for cable length longer than 50m.

I have been using a Motorola Canopy 24V power shot on my link for about 2 months now. I had 3 radio's die at my house before I put the bigger power supply in. So now the 4 radio has a 24V power supply and hasn't missed a beat yet. Seems like someone from SB mentioned once before to never put anything over 24V which gave us the idea. He said DO NOT USE A 30V POWER SUPPLY. Anyways my 24V power shot has been working great. Only down side is that I can't default the radio with the Canopy power shot.
