I'm sure you guys know what they are and probably hate them, but I was wondering where they can be purchased and what the correct term was for them. Are they just called captive WiFi antennas or what? I'm going to need a bunch of antennas our wireless S/PDIF project and I'd like to idiot proof them, because I fear the first thing some of the less electronically inclined users will try operating them with the antenna removed for an extended period of time and burn out the PA as a result.

Thanks,
Stu
