Off topic but part of the discussion on wires,

Replying to the vibration part of the earlier discussion, we have a 46'
parabolic dish that moves at 15 degrees per second and we continiously have
the crimp connector fail on a bi-yearly basis. We have done engineering
studies with solid wire, braided wire, soldered connectors and crimped
connectors but they all failed. The solid conductor seemed to fail earlier.
We think it is weird and have replaced the entire cable harness twice (cost
was in the hundred of thousands) but the problem continues. Our other 46'
antennas do not have this problem.

This is simple, the worker is not holding his mouth right while
assembling the harness. Meindert will want to insist that it is caused
by bad juju but I don't agree. :)

Actually, I am thinking that some vibration must be reaching the
connection and wondering how well the cable is supported and how close
to the connector. And there may be some issues with cyclical heating
and cooling.
