You can find other 802.11b antenna experiments in Finland and in Belgium with HomeMade antennas (this is in french, sorry).
The 'KoekelBerg2 experiments' show the signal strength for a 3.9 km link with home made helicals and tin cans. We also got -85/-98 dBm with a can on a side and a simple lambda/4 wire on the other (the measure is on this side).
We don't know if the apparent better performance of tin cans over helical antennas (which are much more difficult to build) is due to some error in our helical design (based on Jason Hecker's design) or not.
I've got some other links
here
And, just a note about dB's : adding 6 dB allows you to double the distance.

There is an article by Cringely the pulpit : The Death of TCP/IP, Why the Age of Internet Innocence is Over which explain the symbiosis between MS and the viruses. It has already been slashdotted on TCP/MS, We'll Cure What Ails You.
