I thought Computer Bild was the worst of all so called computer related online magazines. Seems as if I was wrong - just stumbled across another DIY WiFi antenna article, thank you google, that was worth quite a laughter!

Besides the common rubbish about legal issues with overpowered antennas, the german online magazine PC Praxis appears to have managed describing transmit power through bandwidth. Something like that is usually worth a nobel prize, though I guess in this case, they would want to check their facts again and maybe stop to contract out authoring to the facility management service 8)
Funny enough, they are also very fuzzy about the EIRP, the unidirectional transmit power figure. They claim 100mW to be ok without any further information, strictly speaking - wrong again. Those 100 mW apply only to a totally equal distribution, which is impossible due to the directional behaviour of electromagnetical waves in this band. With real antennas and real directivity patterns you almost always need to lower the tx power (unless the damping on the link cable is really bad), if you care for those regulations.
