A theoretical model for path gain in suburban Fixed Wireless Access links is found to be within 2.9 dB RMS error of measurements collected at 28 GHz, using a specialized narrowband channel sounder. The measurements were done with a 55 degrees (10 dBi) transmit antenna on an exterior of a house, usually behind foliage, and a 10 degrees (24 dBi) receive horn antenna at 3 m height, emulating a lamp post-mounted base station. The 10 degrees base horn antenna was spun at speeds up to 300 rpm to capture azimuthal angular power distribution.
