When I used this plastic box with a radio astronomy rig, it had a nice warm LNA line driver amp inside.
One cold night, I went out and unlocked the box to find a whole colony of field mice
had made their home there. There was about a pound of lint and little pieces of whatever they could find with an R-factor.
Anyways, I had to fatten up the wires going into the box, so there weren't any little cracks they could squeeze into.
If you look closely at the old coax cable on the left side,
you can see that I wrapped the big ball of metal duct tape around the cable.
Since they never came back, I figure that field mice don't like the feel of shiny metal on their little rat-teeth..
