I spent some time searching for a good external transmitter a while back.
Turns out they're heavily regulated by the FCC. It all boils down to the requirement that you can't interfere with anyone else's reception. Any transmission strength that gives acceptable quality would do that. So they are artificially stunted.
It's possible that your N900 is exceeding legal signal strengths.
