as far as I know, 1142 can use the same power injectors as other APs as they don't consume more power like 1250s do.
The behavior you describe looks normal to me depending on the client behavior. If you hide your SSID, the beacons don't contain the SSID name so the client might not have it easy to show power levels etc ...
I know that lightweight APs hide the ssids even more than IOS APs, in the way that they don't even respond to broadcast blank probe requests. Maybe this behavior was also brought to the 1140 IOS ... that would be the only explanation I see. So in anyway, it would be a consequence of your desire to hide the SSID. You can't totally hide it and still be able to get informations about it. It's a choice to make :-)
It's for sure not related to the wep or wpa encryption difference at least.
