Plugging an arbitrarily-chosen antenna into a WiFi radio (access point

Hi Dave,

At the risk of becoming a stockade-lawyer, I've perused the band plans
(I presume that the 13cM band has not been confiscated in the past few
years), and I think I am reasonably adept at the law in this regard.
As WiFi shares our allocation; it is noteworthy that we as amateurs
are the ONLY service that does NOT require FCC type acceptance to
operate. To my mind, the only issue is one of knowingly interfering
with a service (that doesn't seem to be an issue, however).

One does, of course, need to operate at a frequency in the ham bands
(some of the 802.11 channels are not in the ham bands...)

Some of the fancier WLAN gear is perfectly ok for Part 15 (with
appropriate antenna) but cannot work as amateur gear (because it
radiates out of the ham band).
