| Cantenna is a commercial antenna styled and designed after the famous Pringle's can design but rather better made than most homebrew attempts. There's a discussion on WABUG about whether it is legal in the USA to sell these things as they do not appear to have been FCC certified with specific WiFi cards, APs and cable setups. It appears that for consumer electronics WiFi gear to be sold in the USA it must be certified as a complete setup including the antenna. This perhaps explains why so few Cards and APs have an antenna socket as standard and also why perhaps brand name antennas are fairly expensive. Does anyone know the corresponding legal restrictions in the UK? Is it legal to:- - Build and attach your own antenna - Mix and match electronics and antennas from different manufacturers? Of course, now we've got the legalities out of the way, we'll all just ignore them and do our own thing on the basis that we're highly unlikely to get caught. But even with WiFi's relatively short range, it's important that you have a little clue about what you're doing as particularly if you get into power amps and overdriving the output stages, it's fairly easy to generate large amounts of interference.
