Measurement Procedure and Results Using a Rohde & Schwarz EPSI Spectrum Analyzer connected to a laptop for data gathering purposes, several hours of data were collected over a contiguous range of frequencies between 30MHz and 3GHz. The measurement equipment was placed in an electromagnetically shielded enclosure to ensure the cleanest possible spectrum readings. Two types of antennae, each with particular benefits for use at frequencies above and below 1GHz, were mounted above the highest point of the roof, feeding signals to the spectrum analyzer via several meters of RG-8 coaxial cable.
