Antenna height dependence of 800 MHz attenuation measured in houses

Signal levels around and within four suburban houses were measured at 800 MHz. The measurements were made from an instrumentation van having erectable 27-ft and 12.5-ft-high antennas. The dependence of attenuation on the height of antennas is needed in designing portable radio communication systems that can accommodate low-power radio communication sets. The height dependence of the trends in the data are consistent with the simple model of reflection from the ground.
