"Double the amperage" is nonsense... These power supplies are
constant-voltage, the amperage is merely reporting how much current is
available. Go into any <strike>Radio Shack</strike> and they will tell you
that you need to match the voltage of the power supply, and EXCEED the
Amperage <>Oh, wait...</>.

The problem is that there is a TON of PoE equipment out there that doesn't
follow 802.11af...

I'm not an expert in Ubiquity expert, but there are also a ton of Amateur
Radio operators out there using Bullet M2-HPs on field deployable
networks... How are they powering them?
