i might as well start a new category, which i'm sure will prove useful over time for others.

i have a huge, hi-gain, semi-parabolic Wi-Fi antenna, which i bought last year from a broadcaster's industry supplier in England for hefty bucks + freight, but never used.

It is some giant amount of gain, i believe it is 17 decibels (don't have it here). It's heavy duty wire mesh construction, rectangular, in about 1-1/2 foot or perhaps Closer to 2 goot size, as i recall. It has heavy duty mast clamp hardware, and a short, thick, low-loss, coaxial cable with large-ish (about 1/2" or so?) diameter threaded connector. Adapters can be found to convert yo smaller sizes. (See O'Reilly's excellent, detailed book on setting up communuty wireless networks!)

I paid something outrageous like $50 or so for shipping (was all hot on the idea of having nice, strong signal, long-distance wi-fi from outlying places remote to access points), so total was something like $178 or somethingnin there. Moving, consolidating things i mean to but don't actually use. Make me an offer on this; will settle for about half what i paid. Great for a community wireless network geek who wants something mondo-serious. If in an outlying area, pointed at a specific signal, used as a link, the narrow, focused signal propogation of this directional antenna could disregard spurious, distracting 'noise' signals, and give/receive a Ve y directed signal link.

Due to being semi-parabolic, its narrowly focused signal should also cause much less interference to non-target receivers than a cheaper, plain old global, omnidirectional antenna, thus much more likely keeping you in compliance with FCFC Part 15 rules of not causing undesired interference to anyone else.

(Of course, up to you to responsibly test this by going with mobile receivers to non-target areas and be sure you fine tune its direction, angle, input power, etc. to be sure you achieve the best mix of achieving your remote link, plus remaining within non-interference compliance.)

Let me know if interested. This is in San Francisco. Want to sell locally, not deal with, hassle, packing, transporting, risks and expenses of shipping.

Will also trade for any of following:

An iPod (older model is fine).

A semi-decent digital camera.

A large memory card (512 Meg CF, or possibly 256 Meg working SD/MMC).

A very large capacity (512M) USB pen-drive.

A smaller capacity (128M?) combo WiFi + memory CF card.

Thanks.
