many years ago I read a very good article on the "rusty bolt effect"

cans in the undergrowth.

The rusty bolt (intermodulation) problem can be quite severe e.g. with
repeaters in a commercial site with lots of high power transmitters.

Are the coke cans made of iron ?
Anyway, there would have to be a metal to metal contact that has
oxidised in order to have this kind of junction problem, so I do not
understand how thrown away cans could normally create such junctions.
