This document presents results and modeling updates from measurements conducted in an open roadway scenario featuring trees with a specific z-axis offset. The study includes two types of continuous waveform measurements, capturing data both while passing by the antenna and from stationary antenna positions. Two antenna types were employed - an omnidirectional and a 120-degree directional antenna. A two-ray model was utilized for the analysis, revealing a log-normal process in decibels that approximately increases linearly with distance. The findings contribute to improved understanding and modeling of communication channels in urban environments.
