Term - A passive repeater is an antenna designed to make your link turn a corner without using any electronics or power.
* Robert Cringely talks about his use of a pair of pringle can antennas (actually 4) to create a passive repeater to bounce his signal off a mountain that is 1.5 miles away. The distance from the repeater to the final destination is not mentioned. http://www.pbs.org/cringely/pulpit/pulpit20020207.html
Note that some people dispute that he actually got the passive repeater to work, some discussion here

* One way to perhaps make a quick and dirty passive repeater is to use two existing antennas and connect them together using a N-connector male to male coupler.
