Note that none of this equipment was originally made for 802.11b-specific markets and that careful reading of the device and antenna specifications, paying attention to ohms and milliamps and such, is indicated. Jameco's phone number is 800-831-4242. I haven't looked recently but NASA Tech Briefs (the magazine) is a great source of space-age supplies (duh :-); specifically, things like EMF shielding materials and the like. Warner, you might want to check them out WRT tin foil equivalents. Both of these are on the Web, I suppose, but I leave digging them up as exercises for interested readers. I suppose somewhere on the 'Nyet there may be a compendium of 802.11b antennae wisdom, by now, that we could all stand to reference ... if not, maybe someone should start one. I went looking for the 802.11b specifications and encountered indications that they are accessible only to IEEE members. Anyone have a URL to a public copy? (That goes for all of 'em; 802.11[a-z].) You'd think they'd be on a server, *somewhere* on the UC Berkeley campus ... -- richard -- Richard A Childers/KG6HAC -- Senor UNIX System & Network Administrator "Dont forget nothing."
