What wifi antennas would work as repeaters?

Something that was used in this article:http://www.pbs.org/cringely/pulpit/2002/pulpit_20020207_000721.html (like the 2 yagis he mentioned he mounted on the trees)? So basically an antenna, or maybe a pair, mounted between two points to get the signal around a patch of trees/buildings. Thanks.

Here's what he may have done:

However, a passive repeater isn't a great solution. I took the time to read up on this guy's project, and while it worked... it didn't work very well. There's a good reason why a repeater is usually active. YMMV

An active (powered) repeater is probably your best solution. You can make one out of some routers, either with custom firmware or sometimes supported out of box. There's other solutions but this could be cheapest. Of course that depends on your ability to provide electricity. Best of luck!
