While searching for an Alfa AWUS036h I see a 500mW and a 1000mW output. It seems a different power level would be a different model number. I do note that the 500mW unit has a 2db gain antenna and the 1000mW unit has a 5 db gain antenna. This makes me think the two adapters are the same. I don't use the standard antenna, so if they are the same I'd just as soon purchase the cheaper one rated 500mW. Any comments? Mikek
