ok... so if you goto say.... 150 feet... you need to use the 18v... but would it be better to use the 24v when your nipping at that 310 foot mark?

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.
