It's the senility.
I'm a network guy and I also am pretty damn sure that it's 50ohm. That's actually why we picked it! Forgot about the frequency issues though... oh well.

we all agree in principle; the network coax is really not designed for the 2.4GHz range.

That's exactly what I expected. We will replace all the cable and connectors from the pigtail right through to the antenna with the proper gear and give it another go. Hopefully our yagi will then take us out of card range without passing only corrupt packets. :P

If you are just out wardriving, 500m is probably unrealistic under most circumstances. I have done it but it is rare. 50 to 100m is probably a lot closer to average.

Damn. Oh well... sitting 50m from a building with a big funny antenna doesn't seem as fun as what we had in mind.
We'll see what we can do though. I guess having a yagi with good gain doesn't help all that much when you're trying to talk to a low-power, low-gain omni. Make sense, I just don't like it!

However, I've made point-to-point connections at well over 2k, using directional antennae.

Maybe I'll look into building a cheap repeater.

Dishes are usually a pretty tight beamwidth. About 15 degrees or so. At 30 dregrees, you may or may not get any signal. It is hard to say without actually trying.

Fair enough. I expected the tight beamwidth (hey that's what they're for after all!), but I'll definately try out the more likely looking ones just in case.
Thanks a lot for the replies, I'm more confident than a few days ago, but still a bit disappointed that we can't sit with the antenna in the back seat 3km away from our mark
Oh well, we'll figure something out.
