I am looking to set up a laptop on a boat that will receive wifi
signals. I need to install a twenty foot cable from the antenna to a
cable connector which attaches
Proxim orinoco 8011b/g gold wireless card. I think I have found the
cable but
don't know what antenna to attach to it as I want to minimize loss of
signal and I believe I have to get a certain length antenna to
synchronize with the cable length to do this. Does anyone know what the

right size antenna should be? Also, any suggestions on where to pick
one
up?
I found the cable here

Unless you know where the access point is located and want to fiddle with
aiming it, go with an omnidirectional one. I would go over an 8db gain. I
use a 6 db gain and it works fine. They are getting to be very widely
available. I know CompUSA sells both interior and exterior ones.

That should have read, I would NOT go over 8db

Thanks John. could you tell me what length the antenna should be
itself. I have been told that length will affect the strength of the
signal going out of a longer antenna even if its omnidirectional

Mine, must be about 15" or so. I am not too knowledgeable in antenna design
and leave the length calculations up to the manufacturers. Unless your
trying for really extraordinary range, you can't go too wrong with any
designed for the wi-fi band (about 2.45 GHz for 802.11b,g and n. 80211.a is
at 5 Ghz)

If you need more detail, maybe one of the antenna experts will weigh in.

Where are you going? I did WiFi in Anacortes, Roche Harbor
and Friday Harbor. 4/5 bars. 1-5MBs. I'm using a Fujisu
S6220 notebook--no external antenna.
