I don't care about rep, only facts.

The measured transmit power of the SH in stock configuration is around 17.5dBm at the card, the antennas are basically a perfect 1/4 wavelength dipole, add the transmit power and the raw antenna gain (2.7dB) together and you've got 20.2dBm being radiated in a perfect sphere. That's exactly bang on the legal limit (20dBm), at least when considering measurement error.

In theory at least, the wireless hardware of the Superhub is as near enough "perfect" as theoretically possible - for coverage at least, not performance or reliability - you cannot get a stronger or more even wireless signal out of any device without breaking the law.

The only problem is the computed reflection coefficient, which if correct, indicates up to 80% of the signal reaching the antenna is being bounced back as a result of impedance mismatch.

Assuming that final point (which I cannot verify) is wrong, there's absolutely nothing wrong with the Superhub wireless, from a signal strength point of view. The rest of the problems must be firmware or quality control (or performance, since only one antenna is covering most areas whereas two is needed for optimal speeds). That and the big circuit board blocking off 1/4 of the wireless hardware...
