[Antennas] Can we talk about WLAN antennas here?

[David Robbins K1TTT]

Just remember though, if you are operating outside the limits of the
unlicensed assignment you must:
1. stay on the proper channels, not all of them stay within the amateur
allocation.
2. obey all the other amateur regulations, especially commercial use
limitations which would make it illegal to visit many web sites, let
non-hams exchange email or im with certain countries, and probably lots of
other nasty little gotcha's.
3. you would of course also have to be in control whenever it was being used
by a non-ham...something they may not understand when they try to use it
after you go to bed or leave the house and turn it off.  And to make sure
you were staying legal you would have to monitor all the transmissions,
which could be hard with normal packet sniffers... especially if the user
visited a secure site, so they would be off limits also.  And you would have
to have a way to cut off non-compliant users, something they may not
understand very well either.
