hehe -- getting gain at the antenna isn't such a big deal ... getting the
goo TO the antenna is a whole 'nuther can of worms. It's pretty easy to
come up with 10 dB of gain and 20 dB of feedline loss! Of course, for WiFi,
we're often interested in gain AND omnidirectional -- that is something of a
challenge.

POE! POE! POE! (Power over ethernet). Put the access point at the antenna,
run a cat-5 cable (4 twisted pairs) to it. Four get used for the network
connection, 4 get used for DC.

Not only does it work well, but CAT-5 wire is cheap, 2.4gHz low loss coax
is not.
