In this White Paper I investigate the effect that a metal enclosure has on cell signal strength. A frequent question that we have is how can we get a cell signal out of a metal transformer enclosure without drilling and running wires out? Can a Cell Revolution along with its antenna be installed inside a metal enclosure and actually work? The answer is sometimes, it depends on several factors that I will cover in this paper. For this white paper some simple experiments were preformed in order to answer these questions and demonstrate the best approach for antenna placement inside a metal enclosure.

This white paper includes:

• Understanding antennas
• Enclosures leak RF
• Communication range
• Internally generated noise in the enclosure
• The experiment
