How close are you putting the amps to the radios. Generally you should
only use an amp if you have a long cable run. For example every 50 feet of
LMR400 will cost you 3db. You mount your amp next to your antenna 50 to
100 foot cable run to your radio will cause 3 to 6 db of loss. Every amp I
have seen will handle 20db incoming so you would be okay. Cutting power to
use an amp isn't making sense.
A better choice would be to use a small embedded board from Soekris or
PcEngines and mount your AP next to the antenna and skip the amps.
I have about 30 amps that I have taken out I would give somebody a good
deal on them if they really want to use an amp.
A little more detail on your physical installation would help I don't
think you should have to cut the power down to use an amp
